CHAPTER 6 8-BIT TIMER/EVENT COUNTERS 5 AND 6

(4) 8-bit timer mode control register 6 (TMC6)

This register enables/stops operation of 8-bit timer register 6, sets the operating mode of 8-bit timer register

6 and controls operation of 8-bit timer/event counter 6 output control circuit.

It sets R-S type flip-flop (timer output F/F 1,2) setting/resetting, active level in PWM mode, inversion enabling/

disabling in modes other than PWM mode and 8-bit timer/event counter 6 timer output enabling/disabling.

TMC6 is set with a 1-bit or 8-bit memory manipulation instruction.

RESET input sets TMC6 to 00H.

Figure 6-6. 8-Bit Timer Mode Control Register 6 Format

Cautions 1. Timer operation must be stopped before setting TMC6.

2. If LVS6 and LVR6 are read after data are set, they will be 0.

3. Set 0 to the bits 4 and 5.
