(a) Custom code
The custom code, which consists of 13 bits (C0 to C12)in all, is used to distinguish between receiving sets.
C6 to C12 are fixed by the mask ROM and C0 to C5 are pin-settable.
The custom codes are controlled by Sanyo to avoid duplication.
(b) Key data
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.
