XBAR Module¶

The crossbar or X-BAR API is a set of functions to configure the three X-BARs on the device–the Input X-BAR, the Output X-BAR, and the ePWM X-BAR. The X-BARs route both signals from pins and internal signals from IP blocks to a degree beyond what is possible with GPIO muxing alone. Functions are provided by the API to configure the various muxes, enable and disable signals, and lock in the configurations selected.

Functions

void XBAR_enableOutputMux(uint32_t base, XBAR_OutputNum output, uint32_t muxes)¶

Enables the Output X-BAR mux values to be passed to the output signal.

This function enables the mux values to be passed to the X-BAR output signal. The

output parameter is a value XBAR_OUTPUTy where y is the output number between 1 and 8 inclusive.

Parameters

base: specifies the X-BAR Enable register base address.
output: is the X-BAR output being configured.
muxes: is a bit field of the muxes to be enabled.

The base parameter can take base addresses OUTPUTXBAR_BASE or CLBOUTPUTXBAR_BASE.

The muxes parameter is a bit field of the muxes being enabled where bit 0 represents mux 0, bit 1 represents mux 1 and so on. Defines are provided in the form of XBAR_MUXnn that can be OR’d together to enable several muxes on an output at the same time. For example, passing this function ( XBAR_MUX04 | XBAR_MUX10 ) would enable muxes 4 and 10.

Return: None.

void XBAR_disableOutputMux(uint32_t base, XBAR_OutputNum output, uint32_t muxes)¶

Disables the Output X-BAR mux values from being passed to the output.

void XBAR_setCLBMuxConfig(XBAR_AuxSigNum auxSignal, XBAR_CLBMuxConfig muxConfig)¶

Configures the CLB X-BAR mux that determines the signals passed to a CLB module.

This function configures an CLB X-BAR mux. This determines which signal(s) should be passed through the X-BAR to an CLB module. The

The muxConfig parameter is the mux configuration value that specifies which signal will be passed from the mux. The values have the format of XBAR_CLB_MUXnn_xx where the ‘xx’ is the signal and nn is the mux number (0 through 31). The possible values are found in xbar.h

This function may be called for each mux of an output and their values will be logically OR’d before being passed to the signal. This means that this function may be called, for example, with the argument XBAR_CLB_MUX00_ECAP1_OUT and then with the argument XBAR_CLB_MUX03_INPUTXBAR2, resulting in the values of MUX00 and MUX03 being logically OR’d if both are enabled. Calling the function twice for the same mux on the output will result in the configuration in the second call overwriting the first.

Return: None.

The functions used to configure the ePWM and the Output X-BAR are identifiable as their names will either contain the word EPWM or Output. Both of these X-BARs have multiple output signals that have 32 associated muxes. The select signal of these muxes is configured using the XBAR_setEPWMMuxConfig() and XBAR_setOutputMuxConfig() functions. Each of these mux signals can be enabled and disabled before they are logically OR’d together to arrive at the output signal using XBAR_enableOutputMux() and XBAR_disableOutputMux() and XBAR_enableEPWMMux() and XBAR_disableEPWMMux().

The functions XBAR_getInputFlagStatus() and XBAR_clearInputFlag(), despite their names, are not related to the Input X-BAR. They provide a way to get and clear the status of the signals that are inputs to the ePWM and Output X-BARs. Since these two X-BARs share nearly all of their inputs, they share this set of flags.

The Input X-BAR takes a signal of a GPIO and routes it to an IP block destination. This pin can be selected for each input using the XBAR_setInputPin() function. Note that the descriptions for the values of the XBAR_InputNum enumerated type provide a list of the possible destinations for each input.

The code for this module is contained in driverlib/xbar.c, with driverlib/xbar.h containing the API declarations for use by applications.
