(a) Custom code
The custom code, which consists of 13 bits (C0 to C12) in all, is used to distinguish between receiving sets.
Pin-selectable
6 bits
Mask ROM
7 bits
C6 to C12 are fixed by the mask ROM and C0 to C5 are pin-settable.
In this example C0 to C5 are
set as follows:
C0 C1 C2 C3 C4 C5
011001
The custom codes are controlled by Sanyo to avoid duplication.

When multi-press of key No.20 and one of key No.21, 22, 23 is done, multi-bit D5 will be set to ‘‘1’’, with no priority given
in key entry.
