C-SKY multi-processors timer is designed for C-SKY SMP system and the regs are
|
|
accessed by cpu co-processor 4 registers with mtcr/mfcr.
|
|
|
|
- PTIM_CTLR "cr<0, 14>" Control reg to start reset timer.
|
|
- PTIM_TSR "cr<1, 14>" Interrupt cleanup status reg.
|
|
- PTIM_CCVR "cr<3, 14>" Current counter value reg.
|
|
- PTIM_LVR "cr<6, 14>" Window value reg to trigger next event.
