R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-3 Unimplemented: Read as ‘0’

111 = Reserved
110 = Divide-by-64
101 = Divide-by-32
100 = Divide-by-16
011 = Divide-by-8
010 = Divide-by-4
001 = Divide-by-2
000 = Divide-by-1, maximum PWM timing resolution (power-on default)
Note 1: These bits should be changed only when PTEN = 0. Changing the clock selection during operation will
yield unpredictable results.
