I
High
SERIAL DATA INPUT: Serial data input to the 82C52 receiver circuits. A Mark (1) is high, and a
Space (0) is low. Data inputs on SDI are disabled when operating in the loop mode or when RST is
true.
DR
26
O
High
DATA READY: A true level indicates that a character has been received, transferred to the RBR, and
is ready for transfer to the CPU. DR is reset on a data READ of the Receiver Buffer Register (RBR)
or when RST is true.
VCC
27
High
VCC: +5V positive power supply pin. A 0.1F decoupling capacitor from VCC (Pin 27) to GND (Pin
16) is recommended.

CHIP SELECT: The chip select input acts as an enable signal for the RD and WR input signals.
