Value Description
Active Counter-Compare D Load from Shadow Select Mode:
00 Load on CTR = Zero: Time-base counter equal to zero (TBCTR = 0x0000)
01 Load on CTR = PRD: Time-base counter equal to period (TBCTR = TBPRD)
10 Load on either CTR = Zero or CTR = PRD
11 Freeze (no loads possible)
Note: Has no effect in Immediate mode.
Active Compare C Load from Shadow Select Mode:
00 Load on CTR = Zero: Time-base counter equal to zero (TBCTR = 0x0000)
01 Load on CTR = PRD: Time-base counter equal to period (TBCTR = TBPRD)
10 Load on either CTR = Zero or CTR = PRD
11 Freeze (no loads possible)
Note: Has no effect in Immediate mode.
Value Description
00-FFh These 8-bits contain the high-resolution portion (least significant 8-bits) of the counter-compare A
value. CMPA:CMPAHR can be accessed in a single 32-bit read/write.
