The high-order 8 bits function as an 8-bit length pulse width modulator
using this pulse as input. Its operation is the same as for 16-bit length
pulse width modulator except it has a length of 8 bits. If the high-
order 8 bits’ contents of the reload register is m, the duration “H” of
pulse is
Therefore, if the low-order 8 bits of the reload register is n, the period
of the generated pulse is
