IA186EM/IA188EM
8/16-BIT Microcontrollers
The value of these registers is 000Fh at reset.
DMA1CON/INT6CON (036h) – DMA and INTerrupt CONtrol Register. DMA0CON/INT5CON (034h)
Master Mode
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.
DMA1CON/INT6 (036h) – DMA and INTerrupt CONtrol Register.
DMA0CON/INT5 (034h)
Slave Mode
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.
Reserved (bits 15-4) – Set to 0.
MSK (bit 3) – 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.
PR2-PR0 (bit 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 at reset. The values of PR2 – PR0 are
shown in the above table (Priority Level).
Reserved (bits 15-4) – Set to 0.
MSK (bit 3) – 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.
PR2-PR0 (bits 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 at reset. The values of PR2 – PR0 are
shown in the above table (Priority Level).
