7.2 Configuration of 8-Bit Timer/Event Counters 50 and 51
(1) 8-bit timer counter 5n (TM5n)
8-bit timer/event counters 50 and 51 include the following hardware.
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 input
<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
