Module Stop Control Register B (Mstpcrb) - Renesas H8S/2633 Series Hardware Manual

Bit 0—Clock Select (CKS): Selects the PWM D/A resolution. If the system clock (ø) 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
1 Operates at resolution (T) = system clock cycle time (t

Module Stop Control Register B (MSTPCRB)

Bit :
MSTPB7
Initial value : 1
R/W : R/W
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.
Bit 2—Module Stop (MSTPB2): Specifies PWM0 module stop mode.
Bit 2
MSTPB2 Description
0 PWM0 module stop mode is cleared
1 PWM0 module stop mode is set
Bit 1—Module Stop (MSTPB1): Specifies PWM1 module stop mode.
Bit 1
MSTPB1 Description
0 PWM1 module stop mode is cleared
1 PWM1 module stop mode is set
