Description
A0

I
Register select. A0 to A2 are used during read and write operations to select the UART
register to read from or write to.
A1
14
I
A2
15
I
CDA42
I
Carrier detect A, B (active LOW). These inputs are associated with individual UART
channels A through B. A logic 0 on this pin indicates that a carrier has been detected by the
modem for that channel.
CDB
30
I
CHSEL
16
I
Channel select. UART channel A or B is selected by the logic state of this pin when CS is a
logic 0. A logic 0 on CHSEL selects the UART channel B, while a logic 1 selects UART
channel A. Bit 0 of AFR register can temporarily override CHSEL function, allowing user to
write to both channel registers simultaneously with one write cycle.
CTSA
40
I
Clear to Send A, B (active LOW). These inputs are associated with individual UART
channels A through B. A logic 0 on the CTSn pin indicates the modem or data set is ready to
accept transmit data from the SC16C2552B. Status can be tested by reading MSR[4].
CTSB
28
I
CS
18
I
Chip select (active LOW). This function selects channel A or channel B in accordance with
the logical state of the CHSEL pin. This allows data to be transferred between the user CPU
and the SC16C2552B.
