(Ncount)
The MPWMSM contains a 16-bit modulus down-counter that counts from the
desired loaded value to 0x0001. The term “bits of resolution” is used in this
document to indicate the size of the equivalent free running binary counter. To
cover the worst case, the number of bits is rounded to the lower number. For
example, if the counter is preset with a value between 128 and 255, it is said to
have seven bits of resolution. If it is preset with a value between 256 and 511, it is
said to have eight bits of resolution, and so on.
The term “resolution” is used in this document to define the minimum MPWMSM
output increment in time units.
