Detailed Description

PINCC26XX Hardware attributes.

intPriority is the PIN driver's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. If the driver uses the ti.dpl interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().

swiPriority defines the priority of the SWI the registered callback function will be called in.

Field Documentation

§ intPriority

uint8_t PINCC26XX_HWAttrs::intPriority

SPI CC26XXDMA Peripheral's interrupt priority.

The CC26xx uses three of the priority bits, meaning ~0 has the same effect as (7 << 5).

(7 << 5) will apply the lowest priority.

(1 << 5) will apply the highest priority.

Setting the priority to 0 is not supported by this driver.

HWI's with priority 0 ignore the HWI dispatcher to support zero-latency interrupts, thus invalidating the critical sections in this driver.

§ swiPriority

uint32_t PINCC26XX_HWAttrs::swiPriority

SPI SWI priority. The higher the number, the higher the priority. The minimum is 0 and the maximum is 15 by default. The maximum can be reduced to save RAM by adding or modifying Swi.numPriorities in the kernel configuration file.
