5.1.37 T2INTCON (03ah), T1INTCON (038h), and T0INTCON (032h) (Slave Mode)
Timer INTerrupt CONtrol Register. The three timers, Timer 2, Timer 1, and Timer 0, each have
an interrupt control register, whereas in master mode all three are masked and prioritized in one
register (TCUCON). The value of these registers is 000Fh at reset (see Table 59).

MSK PR2–PR0
Bits [15–4]—Reserved → Set to 0.
Bit [3]—MSK Mask → Any of the interrupt sources may cause an interrupt if the MSK
bit is 0. If 1, they cannot. The Interrupt Mask Register has a duplicate of this bit.
Bits [2–0]—PR2–PR0 Priority → These bits define the priority of the serial port
interrupts in relation to other interrupt signals. The interrupt priority is the lowest at 7 at
reset. The values of PR2–PR0 are shown above.
5.1.38 DMA1CON/INT6CON (036h) and DMA0CON/INT5CON (034h) (Master Mode)
DMA and INTerrupt CONtrol Register. The DMA0 and DMA1 interrupts have interrupt type
0ah and 0bh, respectively. These pins are configured as external interrupts or DMA requests in
the respective DMA Control register. The value of these registers is 000Fh at reset (see
Table 60).

5.1.39 DMA1CON/INT6 (036h) and DMA0CON/INT5 (034h) (Slave Mode)
DMA and INTerrupt CONtrol Register. The two DMA control registers maintain their original
functions and addressing that they possessed in Master Mode. These pins are configured as
