(2) 8-bit timer mode control register 5n (TMC5n)
256
Note Bits 2 and 3 are write-only.
TMC5n is a register that performs the following five types of settings.
<1> 8-bit timer counter 5n (TM5n) count operation control
<2> 8-bit timer counter 5n (TM5n) operating mode selection
<3> Timer output F/F (flip flop) status setting
<4> Active level selection in timer F/F control or PWM (free-running) mode.
<5> Timer output control
TMC5n can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Remark n = 0, 1
