Digital I/O Power Supply
Pen Interrupt. Open anode output (requires 10k
to 100k
pull-up resistor externally).
Serial Data Output. Data is shifted on the falling edge of DCLK. This output is high
impedance when
CS
is high.
Busy Output. This output is high impedance when
CS
is high.
Serial Data Input. If
CS
is low, data is latched on rising edge of DCLK.
Chip Select Input. Controls conversion timing and enables the serial input/output register.
CS
high = power-down mode (ADC only).
External Clock Input. This clock runs the SAR conversion process and synchronizes serial data
I/O.
