Description
Register select. A0-A2 are used during read and write operations
to select the UART register to read from or write to. Refer to
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
generator divisor latches. BAUDOUT may also be used for the
receiver section by tying this output to RCLK.
