bit 7 bit 0
Legend:
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’
bit 2-0 PCLKDIV<2:0>: PWM Input Clock Prescaler (Divider) Select bits
(1)
111 = Reserved
110 = Divide by 64, maximum PWM timing resolution
101 = Divide by 32, maximum PWM timing resolution
100 = Divide by 16, maximum PWM timing resolution
011 = Divide by 8, maximum PWM timing resolution
010 = Divide by 4, maximum PWM timing resolution
001 = Divide by 2, maximum PWM timing resolution
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.
REGISTER 15-3: PTPER: PWM MASTER TIME BASE REGISTER

PTPER <7:0>
bit 7 bit 0
Legend:
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 15-0 PTPER<15:0>: PWM Master Time Base (PMTMR) Period Value bits
Note 1: The minimum value that can be loaded into the PTPER register is 0x0010 and the maximum value is
0xFFF8.
