Count clock
Data not inverted
Count down from
the reload 0
register set value
Underflow
Superficial
underflow
Because the reload 1 register = H'FFFF,
a superficial underflow is generated,
causing the counter to be loaded with
the content of the reload 0 register
Count down from
the reload 0
register set value
