FLD CONTROLLER
Table 1 Pin description
Function
Apply voltage of 5 V to V
CC
, and 0 V to V
SS
.
Applies voltage supplied to pull-down resistors.
Connect an external capacitor to this pin.
Serial transfer is possible by inputting “L” signal.
Pull-up resistor is built in.
Clock for serial transfer is input.
Read a clock twice with 2 MHz sampling clock and judge if it is a noise or not.
Serial data is input/output.
In input mode, read a clock twice with 2 MHz sampling clock and judge if it is a
noise or not.
Pin for ordinary output or digit output.
At reset this port is set to V
EE
level through a pull-down resistor.
Pin for digit output or segment output.
At reset this port is set to V
EE
level through a pull-down resistor.
