Pulse Width Modulator
Technical Data MC68HC912DT128A — Rev 4.0
238 Pulse Width Modulator MOTOROLA
Read anytime but write only in special mode (SMODN = 0). These bits
are available only in special mode and are reset in normal mode.
DISCR — Disable Reset of Channel Counter on Write to Channel
Counter
0 = Normal operation. Write to PWM channel counter will reset
channel counter.
1 = Write to PWM channel counter does not reset channel counter.
DISCP — Disable Compare Count Period
0 = Normal operation
1 = In left-aligned output mode, match of period does not reset the
associated PWM counter register.
DISCAL — Disable Load of Scale-Counters on Write to the Associated
Scale-Registers
0 = Normal operation
1 = Write to PWSCAL0 and PWSCAL1 does not load scale
counters
PWTST — PWM Special Mode Register (“Test”) $0055
