Therefore, if the low-order 8 bits of the reload register are n, the pe-
riod of the generated pulse is
The high-order 8 bits function as an 8-bit length pulse width modula-
tor 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. If the
