1. Key matrix
The TC9243P, TC9243F enables the setting of maximum 32keys in combination of K0--K7 and Tir-Ta
keys. Further, System Codes are settable in 7bits in combination of Kty-k6 and CODE keys.

It K08, 16, 24 and 32 (the shift key) keys can be pushed simultaneously with other keys (the
normal keys).
However, the simultaneous keying of the shift keys and that of the normal keys are prohibited.
It The system code setting is made by the diode jumper between "CODE" lines and "K0--K6'' lines.
With diode jumper, data code will become "I".
However, if the setting of "CODE" and "Ko~K5" keys is only at one point, the keys are
connectable directly without using the diode jumper.
Further, "S7" key is fixed at "I" and cannot be changed.

When oscillation frequency is 455kHz, signal is output after pulse modulated by 37.9kHz of duty 1/
3, which is a 1/12 division by the carrier generation circuit.
(Caution) In preparing a receiving software, strictly follow the following instructions :
o In case of system codes, the same code is transmitted twice and therefore, always
decode these 2 codes and judge if they agree with each other.
In case of key data codes, always decode a key data code and its reversed code and
judge if they agree with each other.
