8/16-BIT Microcontrollers
SPICON (044h) - Serial Port Interrupt CONtrol Register.
This register controls the operation of the asynchronous serial port interrupt source (SPI, bit 10 in of the
Interrupt Request register)
The value of this register is 001Fh at reset.
WDCON (044h) – WatchDog timer interrupt CONtrol Register.

TC [15:0] (bits 15-0) – Timer Count Value. This register has the value of the current count of the
related timer that is incremented every fourth processor clock in internal clocked mode. Alternatively,
the register is incremented each time the Timer 2 maxcount is reached if using Timer 2 as a prescaler.
Timer 0 and Timer 1 may be externally clocked by tmrin0 and tmrin1 signals.
Reserved (bits 15-5) – Set to 0.
Reserved (bit 4) – Set to1.
MSK (bit 3) – Mask. This bit, when 0, enables the serial port to cause an interrupt. When this bit is 1,
the serial port is prevented from generating an interrupt.
PR2-PR0 (bits 2-0) – Priority. These bits define the priority of the serial port interrupt in relation to
other interrupt signals. The interrupt priority is the lowest at 7 at reset. The values of PR2 – PR0 are
shown in the following table.
