(4) Timer output control register (TOC)
TOC is an 8-bit register that controls the active level of timer output and output enabling/disabling.
The operation of the timer output pins (TO0 and TO1) by the timer/counter 0 is controlled by the low-order 4 bits (the high-
order 4 bits control the operation of the timer output pins (TO2 and TO3 by the timer/counter 2).
TOC can be written to or read with an 8-bit manipulation instruction or bit manipulation instruction. The format of the TOC
is shown in Figure 8-5.
RESET input clears TOC to 00H.
