5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 64-byte FIFOs
7.12 Transmission Control Register (TCR)
This 8-bit register is used to store the RX FIFO threshold levels to stop/start transmission
during hardware/software ow control. Table 20 shows transmission control register bit
settings.
TCR trigger levels are available from 0 to 60 bytes with a granularity of four.
Remark: TCR can only be written to when EFR[4] = 1 and MCR[6] = 1. The programmer
must program the TCR such that TCR[3:0] > TCR[7:4]. There is no built-in hardware
check to make sure this condition is met. Also, the TCR must be programmed with this
condition before auto-RTS or software ow control is enabled to avoid spurious operation
of the device.
7.13 Trigger Level Register (TLR)
This 8-bit register is used to store the transmit and received FIFO trigger levels used for
DMA and interrupt generation. Trigger levels from 4 to 60 can be programmed with a
granularity of 4. Table 21 shows trigger level register bit settings.
Remark: TLR can only be written to when EFR[4] = 1 and MCR[6] = 1. If TLR[3:0] or
TLR[7:4] are logic 0, the selectable trigger levels via the FIFO Control Register (FCR) are
used for the transmit and receive FIFO trigger levels. Trigger levels from 4 to 60 bytes are
available with a granularity of four. The TLR should be programmed for N
4, where N is the
desired trigger level.
7.14 FIFO Ready register (FIFO Rdy)
The FIFO Rdy register provides real-time status of the transmit and receive FIFOs of both
channels.

Description
7:4
FIFO Rdy[7:4]
0 = there are less than a RX trigger level number of characters in the
RX FIFO
1 = the RX FIFO has more than a RX trigger level number of characters
available for reading or a time-out condition has occurred
3:0
FIFO Rdy[3:0]
0 = there are less than a TX trigger level number of spaces available in
the TX FIFO
1 = there are at least a TX trigger level number of spaces available in the
TX FIFO
