When a reload value is set in TLE, the same value is loaded into timer counter E (TCE) as well,
and TCE starts counting up from that value. When TCE overflows during operation in auto-reload
mode, the TLE value is loaded in TCE. Accordingly, the overflow period can be set within the
range of 1 to 256 input clocks.
The same address is allocated to TLE as to TCE.
Upon reset, TLE is initialized to H'00.

PMR4 is an 8-bit read/write register, for switching functions of pin P1₅/IRQ₅/TMOE and for
controlling waveform output from pin TMOE.
Upon reset, PMR4 is initialized to H'0F.
