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 CHPCLKEN: Enable Chop Clock Generator bit
1 = Chop clock generator is enabled
0 = Chop clock generator is disabled
bit 14-10 Unimplemented: Read as ‘0’
bit 9-0 CHOP<9:0>: Chop Clock Divider bits
The frequency of the chop clock signal is given by the following expression:
Chop Frequency = (F
P/PCLKDIV<2:0)/(CHOP<9:0> + 1)
