CHAPTER  7   16-BIT  TIMER  0  TM0

7.4  16-Bit Timer 0 Control Registers

The following three types of registers are used to control timer 0.

• 16-bit timer mode control register (TMC0)

• Capture pulse control register (CRC0)

• Prescaler mode register (PRM0)

(1)  16-bit timer mode control register (TMC0)

This register sets the 16-bit timer operating mode and controls the prescaler output signals.

TMC0 is set with a 1-bit or 8-bit memory manipulation instruction.

RESET input clears TMC0 value to 00H.

Cautions 1. Before changing the operation mode, stop the timer operation (by setting 0 to TMC02).

2. Bit 1 and bits 3 to 7 must be set to 0.
