Legend:
R = Readable bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
x = Bit is unknown
bit 7-6
bit 5
bit 4-3
bit 2-0
Unimplemented: Read as ‘0’
USBDIV: USB Clock Selection bit
Selects the clock source for Low-speed USB operation
1 = USB clock comes from the OSC1/OSC2 divided by 2
0 = USB clock comes directly from the OSC1/OSC2 Oscillator block; no divide
CPUDIV<1:0>: CPU System Clock Selection bits
11 = CPU system clock divided by 4
10 = CPU system clock divided by 3
01 = CPU system clock divided by 2
00 = No CPU system clock divide
Unimplemented: Read as ‘0’
