(4) Timer output control register (TOC)
280
TOC is an 8-bit register that controls output enabling/disabling of the active level of timer output.
The operation of the timer output pins (TO2 and TO3) by timer/counter 2 is controlled by the high-order 4 bits (the low-
order 4 bits control the operation of the timer output pins (TO0 and TO1) by timer/counter 0).
TOC can be read or written with an 8-bit manipulation instruction or bit manipulation instruction. The format of the TOC
is shown in Figure 10-5.
RESET input clears TOC to 00H.
