REV. 2.3.1
2.97V TO 5.5V UART WITH 128-BYTE FIFO
29
IER[6]: RTS# Output Interrupt Enable (requires EFR bit-4=1)
Logic 0 = Disable the RTS# interrupt (default).
Logic 1 = Enable the RTS# interrupt. The UART issues an interrupt when the RTS# pin makes a transition
from low to high.
IER[7]: CTS# Input Interrupt Enable (requires EFR bit-4=1)
Logic 0 = Disable the CTS# interrupt (default).
Logic 1 = Enable the CTS# interrupt. The UART issues an interrupt when CTS# pin makes a transition from
low to high.
4.4
Interrupt Status Register (ISR) - Read-Only
The UART provides multiple 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 give the user the current highest pending interrupt level to be serviced, others are queued up to be
serviced next. No other interrupts are acknowledged until the pending interrupt is serviced. The Interrupt
Source Table, Table 9, shows the data values (bits 0-5) for the interrupt priority levels and the interrupt sources
associated with each of these interrupt levels.
4.4.1
Interrupt Generation:
LSR is by any of the LSR bits 1, 2, 3 and 4.
RXRDY is by RX trigger level.
RXRDY Time-out is by a 4-char plus 12 bits delay timer.
TXRDY is by TX trigger level or TX FIFO empty (or transmitter empty in auto RS-485 control).
MSR is by any of the MSR bits 0, 1, 2 and 3.
Receive Xoff/Special character is by detection of a Xoff or Special character.
CTS# is when its transmitter toggles the input pin (from low to high) during auto CTS flow control enabled by
EFR bit-7.
RTS# is when its receiver toggles the output pin (from low to high) during auto RTS flow control enabled by
EFR bit-6.
4.4.2
Interrupt Clearing:
LSR interrupt is cleared by a read to the LSR register (but flags and tags not cleared until character(s) that
generated the interrupt(s) has been emptied or cleared from FIFO).
RXRDY interrupt is cleared by reading data until FIFO falls below the trigger level.
RXRDY Time-out interrupt is cleared by reading RHR until empty.
TXRDY interrupt is cleared by a read to the ISR register or writing to THR.
MSR interrupt is cleared by a read to the MSR register.
Xoff interrupt is cleared by a read to ISR or when Xon character(s) is received.
Special character interrupt is cleared by a read to ISR or after the next character is received.
RTS# and CTS# flow control interrupts are cleared by a read to the MSR register.
