Port Mode Register 5 (Pmr5); Module Stop Control Register (Mstpcr) - Renesas Hitachi H8S/2194 Series Hardware Manual

13.2.4

Port Mode Register 5 (PMR5)

Bit :
Initial value :
R/W :
The port mode register 5 (PMR5) works to changeover the pin functions of the port 5 and to
designate the edge sense of the event inputs of the Timer B (TMBI).
The PMR5 is an 8-bit read/write register. When reset, the PMR5 will be initialized to H'F1.
See section 11.7, Port 5 for other information than bit 1.
Bit 1: Selecting the Edges of the Event Inputs to the Timer B (PMR51)
This bit works to select the input edge sense of the TMBI pins.
Bit 1
PMR51 Description
0 Detects the falling edge of the event inputs to the Timer B
1 Detects the rising edge of the event inputs to the Timer B

Module Stop Control Register (MSTPCR)

Bit : 7
MSTP15
1
Initial value :
R/W
R/W :
The MSTPCR are 8-bit read/write twin registers which work to control the module stop mode.
When the MSTP14 bit is set to 1, the Timer B stops its operation at the ending point of the bus
cycle to shift to the module stop mode. For more information, see section 4.5, Module stop
mode.
When reset, the MSTPCR is initialized to H'FFFF.
