ROI: Recover on Interrupt bit
1 = Interrupts clear the DOZEN bit, and reset the CPU and peripheral clock ratio to 1:1
0 = Interrupts have no effect on the DOZEN bit
DOZE<2:0>: CPU-to-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⁾
1 = DOZE<2:0> bits specify the CPU-to-peripheral clock ratio
0 = CPU and the peripheral clock ratio are set to 1:1
RCDIV<2:0>: FRC Postscaler Select bits
When OSCCON (COSC<2:0>) = 111 or 001:
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) (default)
000 = 8 MHz (divide by 1)
When OSCCON (COSC<2:0>) = 110:
111 = 1.95 kHz (divide by 256)
110 = 7.81 kHz (divide by 64)
101 = 15.62 kHz (divide by 32)
100 = 31.25 kHz (divide by 16)
011 = 62.5 kHz (divide by 8)
010 = 125 kHz (divide by 4)
001 = 250 kHz (divide by 2) (default)
000 = 500 kHz (divide by 1)
Unimplemented: Read as ‘0’
Note 1: This bit is automatically cleared when the ROI bit is set and an interrupt occurs.
