Bit 1—Output Select (OS): Selects the phase of the PWM D/A output.
Bit 1
OS Description
0 Direct PWM output (Initial value)
1 Inverted PWM output
Bit 0—Clock Select (CKS): Selects the PWM D/A resolution. If the system clock (φ) frequency
is 10 MHz, resolutions of 100 ns and 200 ns can be selected.
Bit 0
CKS Description
0 Operates at resolution (T) = system clock cycle time (t
cyc
) (Initial value)
1 Operates at resolution (T) = system clock cycle time (t
cyc
) × 2

MSTPCRB is an 8-bit readable/writable register, and is used to perform module stop mode
control.
When the MSTPB2 is set to 1, at the end of the bus cycle 14-bit PWM timer 0 operation is halted
and a transition made to module stop mode. When the MSTPB1 is set to 1, at the end of the bus
cycle PWM timer 1 operation is halted and a transition made to module stop mode. See section
24.5, Module Stop Mode, for details.
MSTPCRB is initialized to H'FF by a power-on reset and in hardware standby mode. It is not
initialized in manual reset or software standby mode.
