Description
DATA pin I/O select pin "H": Data input
"L": Data output
When, however, CE pin is in "L", DATA pin is in
high impedance
Crystal oscillator connection pin (f=32.768KHz)
For the capacity of Cg and Cd, refer to the series
composition table
Chip enable input pin (built-in pull-down resistor),
"H": DATA pin allows data input/output
"L": DATA pin is in high impedance
Clock input pin: Data are inputted or output in
synchronization with this clock
When, however, CE pin is in "L", DATA pin is in
high impedance
Serial timer data I/O pin
