phbst8 Not HUART0 Data Set Ready.
This input signals in the HUART0 that the
peripheral (or host) is ready to transmit or
receive serial data
General I/O Port
phbst8 Not request to send.
This pin output state goes Low or High
according to the transmit data is in Tx buffer
or Tx FIFO when hardware flow control bit
value set to one in HUART0 control register. If
Tx buffer or Tx FIFO has data to send, this pin
state goes low. If hardware flow control bit is
zero, this pin output can be controlled directly
by HUART0 control register.
General I/O Port
phbst8 Not Clear to send
This input pin function controlled by hardware
flow control bit value in HUART0 control
register. If hardware flow control bit set to one,
HUART0 can transmit the transmitting data
only when this pin state is active.
General I/O Port
phbst8 Not Data Carrier Detect.
This input pin function is determined by
hardware flow control bit value in HUART
control register. If hardware flow control bit set
to one, HUART0 can receive the receiving
data only when this pin state is active.
