Description
Register select.
A0-A2 are used during read and write operations to select the UART
register to read from or write to.
Channel Select.
UART channel A or B is selected by the logical state of this pin when
the CS is a logic 0. A logic 0 on CHSEL selects the UART channel ‘B’, while a logic 1
selects UART channel ‘A’.
Chip Select (Active-LOW).
This function is selects channel ‘A’ or ‘B’, in accordance
with the logical state of the CHSEL pin. This allows data to be transferred between the
user CPU and the SC16C2552, or the SC16C2552 and the CPU for a channel selected
by CHSEL. MF[0] overrides CHSEL while in the write cycle mode, allowing the user to
write both channel registers simultaneously with one write cycle.
Data bus (bi-directional).
These pins are the 8-bit, 3-State data bus for transferring
information to or from the controlling CPU. D0 is the least significant bit and the first
data bit in a transmit or receive serial data stream.
Signal and power ground.
