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
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.
