I
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.
AS
28
15
I
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.
BAUDOUT
17
64
O
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 specied in the baud generator divisor latches.
BAUDOUT may also be used for the receiver section by tying this output to
RCLK.
