Action Qualifier B Register operating mode:
1 Shadow mode – operates as a double buffer. All writes via the CPU access Shadow register.
0 Immediate mode – only the Active action qualifier register is used. All writes/reads via the CPU
directly access the Active register.
0 Reserved
Action Qualifier A Register operating mode:
1 Shadow mode – operates as a double buffer. All writes via the CPU access Shadow register.
0 Immediate mode – only the Active action qualifier register is used. All writes/reads via the CPU
directly access the Active register.
Active Action Qualifier B 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.
