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
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.
