An interface implemented by all TMS320C28xx devices

This interface is defined to factor common data about this family into a single place; all TMS320C28xx devices extend this interface.

Instance Creation
index URL

XDCspec declarations sourced in ti/catalog/c2800/ITMS320C283xx.xdc
create(String revision);
// Create an instance-object
ARGUMENTS
revision — a string that identifies revision of the CPU to be created.
DETAILS
A "data sheet" for a CPU allows one to get specific attributes for a CPU programatically; e.g., the memory map of the CPU.
Notice that we don't specify CPU registers when we create a a data-sheet; registers are provided as necessary to the other functions defined in this interface. This allows one to more easily get memory maps for several different setting of the registers, for example.
 
ITMS320C283xx.getMemoryMap()  // instance
index URL

Get the memory map that corresponds to the values of the specified registers

XDCspec declarations sourced in ti/catalog/c2800/ITMS320C283xx.xdc
function getMemoryMap(registers);
 
ARGUMENTS
registers — a hash of named registers to values at the time an executable is to be loaded (for example)
DETAILS
If a register is not specified and this register can affect the memory map, the register is assumed to be set to its reset value (the value of the register immediately after a CPU reset).
RETURNS
Returns an array of xdc.platform.IPlatform.Memory objects that represent the memory visible to an executable running on the CPU.
 
ITMS320C283xx.getRegisterSet()  // instance
index URL

The set of valid register names for this CPU

XDCspec declarations sourced in ti/catalog/c2800/ITMS320C283xx.xdc
function getRegisterSet();
 
DETAILS
This function returns the complete set of register names that may be passed to the getMemoryMap() function. This function is only used to enable one to write a "requires contract" for the getMemoryMap() function.
RETURNS
Returns an array of valid register names (strings) for this device; only names from this array are valid keys for the registers argument to getMemoryMap().
