Displaying Function on later pages.
PC3 (KS3) Refer to the PORT B outlined above. All the ports of this PORT C apply to the description
THRU for the PORT B.
PC1 (KS1) In this set, these ports output signals to be used as the signal sources for the key matrix.
This is a free terminal and is not connected to the internal circuits, and this terminal can
be used as a junction land.
Refer to description for pins 38 through 40 outlined above.
KEY 4-bit exclusive input ports. These are normally used as the key-matrix input terminals.
INPUTS When the KIN or the KI commands executed, the conditions of these pins are read into the
RAM data memories designated by the operand portion of these commands.
These ports are so configured that the port C and the LCD 9 LCD 16 can specifically be
used as the key-return signal sources. When these LCD 9 through LCD 16 are used as the
key sources, these keyed signals are output from these corresponding port every 6.7 msec
while displaying keyed information on the display panel of the radio.
Whether these keyed source signals are properly output or not is judged by the TKLT or the
TKLF commands. Accordingly, it is requisite to execute the KI or the KIN commands after
‘a proper command execution of TKLT or TKLF, i.e., after the solid confirmation of key-
source signal outputs.
