Description
Register select. A0 to A2 are sued during read and write
operations to select the UART register to read from or write to.
Refer to
description.
Address strobe. When AS is active (LOW), A0, A1 and A2 and
CS0 CS1 and CS2 drive the internal select logic directly. When AS
is HIGH, the register select and chip select signals are held at the
logic levels they were in when the LOW-to-HIGH transition of AS
occurred.
Baud out. BAUDOUT is a 16 clock signal for the transmitter
section of the UART. The clock rate is established by the reference
oscillator frequency divided by a divisor specified in the baud
generator divisor latches. BAUDOUT may also be used for the
receiver section by tying this output to RCLK.
Chip select. When CS0 and CS1 are HIGH and CS2 is LOW, these
3 inputs select the UART. When any of these inputs are inactive, the
UART remains inactive (refer to AS description).
Clear to send. CTS is a modem status signal. Its condition can be
checked by reading bit 4 (CTS) of the Modem Status Register
(MSR). MSR[0] ( CTS) indicates that CTS has changed states
since the last read from the MSR. If the modem status interrupt is
enabled when CTS changes levels and the auto-CTS mode is not
enabled, an interrupt is generated. CTS is also used in the
auto-CTS mode to control the transmitter.
