SC16C850
2.5 to 3.3 V UART with 128-byte FIFOs and IrDA encoder/decoder
[1]
When RXINTLVL, TXINTLVL, FLWCNTL or FLWCNTH contains any value other than 0x00, receive and
transmit trigger levels are set by RXINTLVL, TXINTLVL registers (see Section 6.4 “FIFO operation”).
7.4 Interrupt Status Register (ISR)
The SC16C850 provides six levels of prioritized interrupts to minimize external software
interaction. The Interrupt Status Register (ISR) provides the user with six interrupt status
bits. Performing a read cycle on the ISR will provide the user with the highest pending
interrupt level to be serviced. No other interrupts are acknowledged until the pending
interrupt is serviced. A lower level interrupt may be seen after servicing the higher level
interrupt and re-reading the interrupt status bits. Table 13 “Interrupt source” shows the
data values (bits 5:0) for the six prioritized interrupt levels and the interrupt sources
associated with each of these interrupt levels.

Bit

Description
7:6
ISR[7:6]
FIFOs enabled. These bits are set to a logic 0 when the FIFOs are not being
used in the non-FIFO mode. They are set to a logic 1 when the FIFOs are
enabled in the SC16C850 mode.
logic 0 or cleared = default condition
5:4
ISR[5:4]
INT priority bits 4:3. These bits are enabled when EFR[4] is set to a logic 1.
ISR[4] indicates that matching Xoff character(s) have been detected. ISR[5]
indicates that CTS, RTS have been generated. Note that once set to a
logic 1, the ISR[4] bit will stay a logic 1 until Xon character(s) are received.
logic 0 or cleared = default condition
3:1
ISR[3:1]
INT priority bits 2:0. These bits indicate the source for a pending interrupt at
interrupt priority levels 1, 2, and 3 (see Table 13).
logic 0 or cleared = default condition
