No.6745-7/13
Sample Application Circuit
(1) Ag battery used application (1/2 bias 1/4 duty)
(Power supply : Ag battery version)
Note 1) If P0, P1 port or segment output (SEG17 to SEG32) are used for key scan output port, P-ch open drain option should
be used in order to prohibit signal short between output ports when two or more keys are pushed simultaneously.
Note 2) If P1 port is used as output port, the following setting is necessary. Programmable pull-down resistors which is one
of the internal pull-down register should be set to open mode with the SPDR instruction.
