REV. 1.0.3
2.25V TO 3.6V HIGH PERFORMANCE OCTAL UART WITH 16-BYTE FIFO
Each bit gives an indication of the channel that has requested for service. For example, bit-0 represents
channel 0 and bit-7 indicates channel 7. Logic one indicates the channel N [7:0] has called for service. The
interrupt bit clears after reading the appropriate register of the interrupting UART channel register (ISR, LSR
and MSR). SEE”INTERRUPT CLEARING:” ON PAGE 34. for interrupt clearing details.

INT0 Channel Interrupt Indicator
3.1.1.2
INT1, INT2 and INT3 Interrupt Source Locator
INT3, INT2 and INT1 provide a 24-bit (3 bits per channel) encoded interrupt indicator. Table 9 shows the 3 bit
encoding and their priority order. The 16-bit Timer time-out interrupt will show up only as a channel 0 interrupt.
For other channels, interrupt 7 is reserved.
