I2C/SPI UART WITH 128-BYTE FIFO AND INTEGRATED LEVEL SHIFTERS
IER[2]: Receive Line Status Interrupt Enable
If any of the LSR register bits 1, 2, 3 or 4 is a logic 1, it will generate an interrupt to inform the host controller
about the error status of the current data byte in FIFO. LSR bit-1 generates an interrupt immediately when an
overrun occurs. LSR bits 2-4 generate an interrupt when the character in the RHR has an error. However,
when EMSR bit-6 changes to 1 (default is 0), LSR bit 2-4 generate an interrupt when the character is received
in the RX FIFO. Please refer to “Section 3.14, Enhanced Mode Select Register (EMSR) - Write-only” on
Logic 0 = Disable the receiver line status interrupt (default).
Logic 1 = Enable the receiver line status interrupt.
IER[3]: Modem Status Interrupt Enable
Logic 0 = Disable the modem status register interrupt (default).
Logic 1 = Enable the modem status register interrupt.
IER[4]: Sleep Mode Enable (requires EFR[4] = 1)
Logic 0 = Disable Sleep Mode (default).
Logic 1 = Enable Sleep Mode. See Sleep Mode section for further details.
IER[5]: Xoff Interrupt Enable (requires EFR[4]=1)
Logic 0 = Disable the software flow control, receive Xoff interrupt. (default)
Logic 1 = Enable the software flow control, receive Xoff interrupt. See Software Flow Control section for
details.
IER[6]: RTS# Output Interrupt Enable (requires EFR[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 (if enabled by EFR bit-6).
IER[7]: CTS# Input Interrupt Enable (requires EFR[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 (if enabled by EFR bit-7).
3.4
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 11, shows the data values (bit 0-5) for the interrupt priority levels and the interrupt sources
associated with each of these interrupt levels.
