CHAPTER 6 8-BIT TIMER/EVENT COUNTERS 5 AND 6
(3) 8-bit timer mode control register 5 (TMC5)
This register enables/stops operation of 8-bit timer register 5, sets the operating mode of 8-bit timer register
5 and controls operation of 8-bit timer/event counter 5 output control circuit.
It sets R-S type flip-flop (timer output F/F 1,2) setting/resetting, the active level in PWM mode, inversion
enabling/disabling in modes other than PWM mode and 8-bit timer/event counter 5 timer output enabling/
disabling.
TMC5 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TMC5 to 00H.
Figure 6-5. 8-Bit Timer Mode Control Register 5 Format
Cautions 1. Timer operation must be stopped before setting TMC5.
2. If LVS5 and LVR5 are read after data are set, they will be 0.
3. Set 0 to the bits 4 and 5.
