ROI
2:
This bit is automatically cleared when the ROI bit is set and an interrupt occurs.
This setting is not allowed while the USB module is enabled.
ROI: Recover on Interrupt bit
1 = Interrupts clear the DOZEN bit and reset the CPU peripheral clock ratio to 1:1
0 = Interrupts have no effect on the DOZEN bit
DOZE<2:0>: CPU Peripheral Clock Ratio Select bits
111 = 1:128
110 = 1:64
101 = 1:32
100 = 1:16
011 = 1:8
010 = 1:4
001 = 1:2
000 = 1:1
DOZEN: DOZE Enable bit
1 = DOZE<2:0> bits specify the CPU peripheral clock ratio
0 = CPU peripheral clock ratio is set to 1:1
RCDIV<2:0>: FRC Postscaler Select bits
111 = 31.25 kHz (divide by 256)
110 = 125 kHz (divide by 64)
101 = 250 kHz (divide by 32)
100 = 500 kHz (divide by 16)
011 = 1 MHz (divide by 8)
010 = 2 MHz (divide by 4)
001 = 4 MHz (divide by 2)
000 = 8 MHz (divide by 1)
CPDIV<1:0>: System Clock Select bits (postscaler select from 32 MHz clock branch)
11 = 4 MHz (divide by 8)
10 = 8 MHz (divide by 4)
01 = 16 MHz (divide by 2)
00 = 32 MHz (divide by 1)
