/**
|
|
* This is based on some quick but sound experiments on PP5022C.
|
|
* CPU/COP_CTL bitmap:
|
|
* [31] - sleep until an interrupt occurs
|
|
* [30] - wait for cycle countdown to 0
|
|
* [29] - wait for cycle countdown to 0
|
|
* behaves identically to bit 30 unless bit 30 is set as well
|
|
* in which case this bit is cleared at the end of the count
|
|
* [28] - unknown - no execution effect observed yet
|
|
* [27] - begin cycle countdown
|
|
* [26:8] - semaphore flags for core communication ?
|
|
* no execution effect observed yet
|
|
* [11:8] seem to often be set to the core's own ID
|
|
* nybble when sleeping - 0x5 or 0xa.
|
|
* [7:0] - W: number of cycles to skip on next instruction
|
|
* R: cycles remaining
|
|
* Executing on CPU
|
|
* CPU_CTL = 0x68000080
|
|
* nop
|
|
* stalls the nop for 128 cycles
|
|
* Reading CPU_CTL after the nop will return 0x48000000
