Register select.
A0-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 generator divisor
latches. BAUDOUT may also be used for the receiver section by tying
this output to RCLK.
