Controlled Noise Suppression
Configuration of the
Receiver
The T5743 receiver is configured via two 12-bit RAM registers called OPMODE and
LIMIT. The registers can be programmed by means of the bidirectional DATA port. If the
register contents have changed due to a voltage drop, this condition is indicated by a
certain output pattern called reset marker (RM). The receiver must be reprogrammed in
that case. After a power-on reset (POR), the registers are set to default mode. If the
receiver is operated in default mode, there is no need to program the registers. Table 4
shows the structure of the registers. According to Table 2 bit 1 defines if the receiver is
set back to polling mode via the OFF-command (see section “Receiving Mode”) or if it is
programmed. Bit 2 represents the register address. It selects the appropriate register to
be programmed. To get a high programming reliability, Bit15 (Stop bit), at the end of the
programming operation, must be set to 0.
