12.5.4 OSCCON3

Oscillator Control Register 3
Note:
  1. If CSWHOLD = 0, the user may not see this bit set (NOSCR = 1). When the oscillator becomes ready, there may be a delay of one instruction cycle before NOSCR is set. The clock switch occurs in the next instruction cycle and NOSCR is cleared.
Name: OSCCON3
Address: 0x07C

Access R/W/HCR/WRR 
Reset 0100 

Bit 7 – CSWHOLD Clock Switch Hold Control

ValueDescription
1 Clock switch (and interrupt) will hold when the oscillator selected by NOSC is ready
0 Clock switch will proceed when the oscillator selected by NOSC is ready

Bit 6 – SOSCPWR Secondary Oscillator Power Mode Select

ValueDescription
1 Secondary Oscillator operates in High-Power mode
0 Secondary Oscillator operates in Low-Power mode

Bit 4 – ORDY Oscillator Ready (read-only)

ValueDescription
1 OSCCON1 = OSCCON2; the current system clock is the clock specified by NOSC
0 A clock switch is in progress

Bit 3 – NOSCR  New Oscillator is Ready (read-only)(1)

ValueDescription
1 A clock switch is in progress and the oscillator selected by NOSC indicates a Ready condition
0 A clock switch is not in progress, or the NOSC-selected oscillator is not ready
If CSWHOLD = 0, the user may not see this bit set (NOSCR = 1). When the oscillator becomes ready, there may be a delay of one instruction cycle before NOSCR is set. The clock switch occurs in the next instruction cycle and NOSCR is cleared.
