IA186ES/IA188ES
8-Bit/16-Bit Microcontrollers
5.1.40 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 61).
Table 61. DMA and Interrupt Control Register (Master Mode)
5.1.41 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
external interrupts or DMA requests in the respective DMA Control register. The value of these
registers is 000Fh at reset (see Table 62).

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. The interrupt sources cannot cause an interrupt if the MSK bit is 1. The Interrupt
Mask Register has a duplicate of this bit.
Bit [2–0]—PR [2–0] 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 upon reset.
The values of PR2–PR0 are shown above.
