TABLE 3-3:
INITIALIZATION CONDITIONS FOR ALL REGISTERS (CONTINUED)
Register
Applicable Devices
Power-on Reset,
Brown-out Reset
MCLR Resets
WDT Reset
RESET
Instruction
Stack Resets
Wake-up via WDT
or Interrupt
Legend: u = unchanged, x = unknown, - = unimplemented bit, read as '0', q = value depends on condition.
Shaded cells indicate conditions do not apply for the designated device.
* These registers are retained to maintain compatibility with PIC18FXX2 devices; however, one or more bits
are reserved. Users should not modify the value of these bits. See Section 4.9.2 for details.
Note 1: When the wake-up is due to an interrupt and the GIEL or GIEH bit is set, the TOSU, TOSH and TOSL are
updated with the current value of the PC. The STKPTR is modified to point to the next location in the
hardware stack.
2: When the wake-up is due to an interrupt and the GIEL or GIEH bit is set, the PC is loaded with the interrupt
vector (0008h or 0018h).
3: One or more bits in the INTCONx or PIRx registers will be affected (to cause wake-up).
4: See Table 3-2 for RESET value for specific condition.
5: Bit 6 of PORTA, LATA, and TRISA are enabled in ECIO and RCIO Oscillator modes only. In all other
Oscillator modes, they are disabled and read ‘0’.
6: Bit 6 of PORTA, LATA and TRISA are not available on all devices. When unimplemented, they are read ‘0’.
