SC16C752B
5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
6.6.2 Block DMA transfers (DMA mode 1)
Figure 11 shows TXRDYn and RXRDYn in DMA mode 1.
6.6.2.1
Transmitter
TXRDYn is active when there is a trigger level number of spaces available. It becomes
inactive when the FIFO is full.
6.6.2.2
Receiver
RXRDYn becomes active when the trigger level has been reached, or when a time-out
interrupt occurs. It will go inactive when the FIFO is empty or an error in the receive FIFO
is flagged by LSR[7].
6.7 Sleep mode
Sleep mode is an enhanced feature of the SC16C752B UART. It is enabled when EFR[4],
the enhanced functions bit, is set and when IER[4] is set. Sleep mode is entered when:
The serial data input line, RXn, is idle (see Section 6.8 “Break and time-out
The transmit FIFO and transmit shift register are empty.
There are no interrupts pending except THR and time-out interrupts.
Remark: Sleep mode will not be entered if there is data in the receive FIFO.
In Sleep mode, the UART clock and baud rate clock are stopped. Since most registers are
clocked using these clocks, the power consumption is greatly reduced. The UART will
wake up when any change is detected on the RXn line, when there is any change in the
state of the modem input pins, or if data is written to the transmit FIFO.
Remark: Writing to the divisor latches DLL and DLM to set the baud clock must not be
done during Sleep mode. Therefore, it is advisable to disable Sleep mode using IER[4]
before writing to DLL or DLM.
