1.8 V dual UART with 128-byte FIFOs and IrDA encoder/decoder
7.22 Advanced Feature Control Register 1 (AFCR1)
Table 34.
Bit
7
[1]
It takes 4 XTAL1 clocks to reset the device.
Advanced Feature Control Register 1 register bits description
Symbol
Description
AFCR1[7]
Concurrent write. When this bit is set the host can write concurrently to
the same register of all channel.
logic
logic 0 = Normal operation
logic 1 = Concurrent Write operation
AFCR1[6:5]
reserved
AFCR1[4]
Sleep RXLow. Program RX input to be edge-sensitive or level-sensitive.
logic 0 = RX input is level-sensitive. If RXA/RXB pin is LOW, the UART
will not go to sleep. Once the UART is in Sleep mode, it will wake up if
RXA/RXB pin goes LOW.
logic 1 = RX input is edge-sensitive. UART will go to sleep even if
RXA/RXB pin is LOW, and will wake up when RXA/RXB pin toggles.
AFCR1[3]
reserved
AFCR1[2]
RTS/CTS mapped to DTR/DSR. Switch the function of RTS/CTS to
DTR/DSR.
logic 0 = RTS and CTS signals are used for hardware flow control.
logic 1 = DTR and DSR signals are used for hardware flow control.
RTS and CTS retain their functionality.
AFCR1[1]
SReset. Software Reset
A write to this bit will reset the UART. Once the UART is reset this bit is
automatically set to 0.
[1]
AFCR1[0]
TSR Interrupt. Select TSR interrupt mode
logic 0 = transmit empty interrupt occurs when transmit FIFO falls
below the trigger level or becomes empty.
logic 1 = transmit empty interrupt occurs when transmit FIFO falls
below the trigger level, or becomes empty and the last stop bit has
been shifted out of the Transmit Shift Register.
