Legend: x = unknown; u = unchanged; - = unimplemented, read as ‘0’; q = value depends on condition; r = reserved bit, do not modify. Shaded cells
are unimplemented, read as ‘0’.
Note 1: Bit 7 and bit 6 are cleared by user software or by a POR.
2: Bit 21 of the PC is only available in Serial Programming modes.
3: Reset value is ‘0’ when Two-Speed Start-up is enabled and ‘1’ if disabled.
4: Alternate names and definitions for these bits when the MSSP module is operating in I
2
C™ Slave mode.
5: These bits and/or registers are only available in 100-pin devices; otherwise, they are unimplemented and read as ‘0’. Reset values shown
apply only to 100-pin devices.
6: These bits and/or registers are only available in 80-pin and 100-pin devices. In 64-pin devices, they are unimplemented and read as ‘0’. Reset
values are shown for 100-pin devices.
7: In Microcontroller mode, the bits in this register are unwritable and read as ‘0’.
8: PLLEN is only available when either ECPLL or HSPLL Oscillator mode is selected; otherwise, read as ‘0’.
9: Implemented in 100-pin devices in Microcontroller mode only.
