INDAR7 INDAR6 INDAR5 INDAR4 INDAR3 INDAR2 INDAR1 INDAR0

Any instruction using the INDF register actually accesses the register pointed by the INDAR register.

Value on POR: “x x x x x x x x” [1]

Note 1: “x” means unknown

PORT1.4 PORT1.3 PORT1.2 PORT1.1 PORT1.0

PORT1 is a 5-bits latch for Port 1.0~Port 1.4. Reading the PORT1 register gets the status of the pins.

Writing to it will write to the port latch. All write operations are read-modify-write operations.

PORT1CON is used to enable/disable every bits of the port latch.

Value on POR: “- - - x x x x x”

PORT2 is an 8-bits latch for Port 2.0~Port 2.7. Reading the PORT2 register reads the status of the pins.

Writing to it will write to the port latch. All write operations are read-modify-write operations.

PORT2CON is used to enable/disable every bits of the port latch.

Value on POR: “x x x x x x x x”

PCHBUF2 PCHBUF1 PCHBUF0

Write buffer for upper 3-bits of Program Counter. The upper byte of Program Counter is not directly

accessible. PCHBUF is a holding register for the PC[10:8] that are transferred to the upper byte of the

Program Counter when branch occur. Please see PCL register to get more detail information.

GIE: Global interrupt enable bit

1: Enable all interrupts

0: Disable all interrupts

TMROEN: Timer overflow interrupt enable bit

1: Enable timer interrupt

0: Disable timer interrupt

TMROF: Timer overflow interrupt flag bit. This bit should be cleared to ‘0’ by firmware after it is set by

hardware.

1: Timer register has overflowed

0: Timer register did not overflow

Value on POR: “0 - 0 - - 0 - -“
