CHAPTER 9 8-BIT TIMER/EVENT COUNTERS 1 AND 2
(3) 8-bit timer output control register (TOC1)
This register controls operation of 8-bit timer/event counter output control circuits 1 and 2.
It sets/resets the R-S flip-flops (LV1 and LV2) and enables/disables inversion and 8-bit timer output of 8-bit
timer registers 1 and 2.
TOC1 is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets TOC1 to 00H.
Figure 9-6. 8-Bit Timer Output Control Register Format
Cautions 1. Be sure to set TOC1 after stopping timer operation.
2. After data setting, 0 can be read from LVS1, LVS2, LVR1 and LVR2.
