13.5 Programming the Registers
Software is programmed through the registers (
Master mode:
44h, 42h, 40h, 3Eh, 3Ch, 3Ah, 38h, 36h, 34h, 32h, 30h, 2Eh,
2Ch, 2Ah, 28h, 26h, 24h, 22h;
Slave Mode:
3Ah, 38h, 36h, 34h, 32h, 30h, 2Eh, 2Ch, 2Ah, 28h,22h, 20h ) to define the
interrupt controller operation.
(Master Mode)
Bit 15-4
: Reserved
Bit 3: MSK
, Mask.
Set 1: Mask the interrupt source of the asynchronous serial port 0.
Set 0: Enable the serial port 0 interrupt.
Bit 2-0 : PR2-PR0
, Priority. These bits determine the priority of the serial port relative to the other interrupt signals.
