An output signal from the slave to the microcontroller. A low signal indicates that
the SC-691 is ready to accept data or command. A high signal indicates that the
SC-691 is busy and the microcontroller must not write any data or command to it
An output signal from the slave to the microcontroller. A low signal indicates that
the SC-691 is ready to send data or command to the microcontroller.

26 I/O General-purpose I/O bus
An input signal to the slave from the microcontroller. Read/write select signal which
is set high for read operations or set low for write operations by the microcontroller.
An input signal to the slave from the microcontroller. STROBE_ sequences read or
write operations in conjunction with the R/W_ signal. This signal is pulsed high-low-
high for read or write operations sequencing.

All pins must be N.C.
Marked pins are
V
DD
and
V
SS
connections which service the DAC circuitry. These pins tend to sustain a higher current draw. A dedicated
decoupling capacitor across these pins is therefore required.
