C-SKY Multi-processors Timer
|
||||
============================
|
||||
|
||||
C-SKY multi-processors timer is designed for C-SKY SMP system and the
|
||||
regs is 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 triger next event.
