[bit4] RELD (reload operation permission)
It is a bit by which the reload operation is permitted. When the RELD is "1", the timer operates in the
reload mode operation. In this mode, the timer loads the reload register content to the counter and
continues the count operation even when an underflow occurs (when the counter value changes from
0000
counter operation stops when the counter value changes from 0000
occurs.

[bit3] INTE (timer interruption demand permission)
This bit permits the timer interrupt request. If the INTE value is "0", no interrupt request is generated
even when the UF value becomes "1".

[bit2] UF (timer interruption demand flag)
It is Interrupt request flag. When the underflow is generated, UF is set in "1". Cleared by writing "0" or
by μDMAC. The read value is "1" when using a read-modify-write instruction.
