(1) 8-bit timer counter 5n (TM5n)
(2) 8-bit timer compare register 5n (CR5n)
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.
CR5n can be read and written by an 8-bit memory manipulation instruction.
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.
The value of CR5n can be set within 00H to FFH.
Reset signal generation sets CR5n to 00H.
Caution Do not write other values to CR5n during operation.
