    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.
    Note 1:
    One or more bits in the INTCONx or PIRx registers will be affected (to cause wake-up).
    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:
    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.
    4:
    See Table 5-3 for Reset value for specific condition.
    5:
    Bits 6 and 7 of PORTA, LATA and TRISA are enabled, depending on the oscillator mode selected. When
    not enabled as PORTA pins, they are disabled and read ‘0’.
