These two inputs provide the reference voltages for the analog-to-digital
(A/D) converter circuitry:
For proper A/D converter operation:
The strobe A (STRA) and address strobe (AS) pin performs either of two
separate functions, depending on the operating mode:
AS can be used to demultiplex the address and data signals at port C.
Refer to
The strobe B (STRB) and read/write (R/W) pin act as either an output
strobe or as a data bus direction indicator, depending on the operating
mode.
In single-chip operating mode, STRB acts as a programmable strobe for
handshake with other parallel devices. Refer to
Input/Output (I/O) Ports
In expanded multiplexed operating mode, R/W is used to indicate the
direction of transfers on the external data bus. A low on the R/W pin
indicates data is being written to the external data bus. A high on this pin
