5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
7.11 Divisor latches (DLL, DLM)
These are two 8-bit registers which store the 16-bit divisor for generation of the baud clock
in the baud rate generator. DLM stores the most significant part of the divisor. DLL stores
the least significant part of the divisor.
Note that DLL and DLM can only be written to before Sleep mode is enabled, i.e., before
IER[4] is set.
7.12 Transmission Control Register (TCR)
This 8-bit register is used to store the receive FIFO threshold levels to stop/start
transmission during hardware/software flow control. Table 20 shows Transmission Control
Register bit settings.
TCR trigger levels are available from 0 bytes to 60 bytes with a granularity of four.
Remark: TCR can only be written to when EFR[4] = logic 1 and MCR[6] = logic 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 flow control is enabled to avoid spurious
operation of the device.
5
EFR[5]
Special character detect.
logic 0 = special character detect disabled (normal default condition)
logic 1 = special character detect enabled. Received data is compared with
Xoff2 data. If a match occurs, the received data is transferred to FIFO and IIR[4]
is set to a logic 1 to indicate a special character has been detected.
4
EFR[4]
Enhanced functions enable bit.
logic 0 = disables enhanced functions and writing to IER[7:4], FCR[5:4],
MCR[7:5]
logic 1 = enables the enhanced function IER[7:4], FCR[5:4], and MCR[7:5] can
be modified, i.e., this bit is therefore a write enable.
3:0
EFR[3:0] Combinations of software flow control can be selected by programming these bits.
