8-bit timer counter Hn
<1> The count operation is enabled by setting TMHEn = 1. Start 8-bit timer counter Hn by masking one count
<2> The CMP1n register value can be changed during timer counter operation. This operation is asynchronous
<3> When the values of 8-bit timer counter Hn and the CMP0n register match, the value of 8-bit timer counter Hn
<4> If the CMP1n register value is changed, the value is latched and not transferred to the register. When the

the CMP1n register and the CMP1n register value is changed (<2>’).
However, three count clocks or more are required from when the CMP1n register value is changed to when
the value is transferred to the register. If a match signal is generated within three count clocks, the changed
value cannot be transferred to the register.
