Timer and DMA Interrupt Control Registers
(TCUCON, Offset 32h, DMA0CON/INT5CON, Offset 34h, DMA1CON/
INT6CON, Offset 36h)
(Master Mode)
The three timer interrupts are assigned to interrupt type 08h, 12h, and 13h. All three timer
interrupts are configured through TCUCON, offset 32h. The DMA0 interrupt is assigned to
interrupt type 0Ah. The DMA1 interrupt is assigned to interrupt type 0Bh. See the DMA
control registers for how to configure these pins as DMA requests or external interrupts.
Timer/DMA Interrupt Control Registers
The value of TCUCON, DMA0CON, and DMA1CON at reset is 000Fh.
Bits 15–4: Reserved—Set to 0.
Bit 3: Interrupt Mask (MSK)—This bit determines whether the corresponding signal can
generate an interrupt. A 1 masks this interrupt source. A 0 enables the corresponding
interrupt.
This bit is duplicated in the Interrupt Mask register. See the Interrupt Mask register in Section
7.3.10 on page 7-24.
Bits 2–0: Priority Level (PR2–PR0)—Sets the priority level for its corresponding source.
See Table 7-3 on page 7-18.
