Register select.
A0 to A2 are used during read and write
operations to select the UART register to read from or write to.
Refer to
Table 3
for register addresses and refer to AS 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 rate
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
three inputs select the UART. When any of these inputs are inactive,
the UART remains inactive (refer to AS description).
