Therefore, if the low order 8-bit of the reload register is n, the pe-
riod of the generated pulse is
The high order 8-bit function as an 8-bit length pulse width modu-
lator using this pulse as input. The operation is the same as for
16-bit length pulse width modulator except that the length is 8 bits.
