Symbol
SIN1/GPIO_P4[4]
SOUT1/GPIO_P4[1]
RTS1/GPIO_P4[2]
Type
Description
Receive Data. FIFO UART receiver serial data input signal.
I/O
General-Purpose Input/Output GPIO port4 [4].
Transmit Data. FIFO UART transmitter serial data output from the serial port.
I/O
General-Purpose Input/Output GPIO port4 [1].
Request to Send. Active low Request to Send output for UART port.
A handshake output signal notifies the modem that the UART is ready to
transmit data. This signal can be programmed by writing to bit 1 of Modem
I/O Control Register (MCR). The hardware reset will clear the RTS_n signal to be
inactive mode (high). It is forced to be inactive during the loop-mode
operation.
General-Purpose Input/Output GPIO port4 [2].
