TM5n is an 8-bit register that counts the count pulses and is read-only.
The counter is incremented in synchronization with the rising edge of the count clock.
In the following situations, the count value is cleared to 00H.
<1> Reset signal generation
<2> When TCE5n is cleared
<3> When TM5n and CR5n match in the mode in which clear & start occurs upon a match of the TM5n and CR5n.
CR5n can be read and written by an 8-bit memory manipulation instruction.
Except in PWM mode, the value set in CR5n is constantly compared with the 8-bit timer counter 5n (TM5n) count
value, and an interrupt request (INTTM5n) is generated if they match.
In the PWM mode, TO5n output becomes inactive when the values of TM5n and CR5n match, but no interrupt is
generated.
The value of CR5n can be set within 00H to FFH.
Reset signal generation clears CR5n to 00H.
Cautions 1. In the mode in which clear & start occurs on a match of TM5n and CR5n (TMC5n6 = 0), do not
