(3) 16-bit timer output control register 0n (TOC0n)
180
TOC0n is an 8-bit register that controls the TO0n pin output.
TOC0n can be rewritten while only OSPT0n is operating (when TMC0n3 and TMC0n2 = other than 00).
Rewriting the other bits is prohibited during operation.
However, TOC0n4 can be rewritten during timer operation as a means to rewrite CR01n (see 7.5.1 Rewriting
CR01n during TM0n operation).
TOC0n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears TOC0n to 00H.
Caution Be sure to set TOC0n using the following procedure.
Remark n = 0 to 3
<1> Set TOC0n4 and TOC0n1 to 1.
<2> Set only TOE0n to 1.
<3> Set either of LVS0n or LVR0n to 1.
