1 : High level (VDD)
0 : Low level (VSS)
2-6 . HLD : Display contents hold pin
Normally, this pin is set at high level. To hold display contents, this pin is set at low level. Connecting time constant circuit
to this pin makes it possible to hold display contents for a certain period of time at the time of FM/MW, LW band
selection.
2-7 . BLK : Display blanking pin
2-8 . FMI, AMI : Local oscillation signal input pins
FMI — For FM
: 0.7Vp-p input sensitivity
AMI — For MW, LW : 1.0Vp-p input sensitivity (VDD =8to10 V,fIN = 0.5 to 0.9 MHz)
0.5Vp-p input sensitivity (other than above)
2-9 . A/F : FM/MW, LW select pin
FM
— Pin open or high level
MW, LW — Low level
