Control register

The ST7538Q is a multi-channel and multifunction transceiver. An internal 24 or 48 Bits (in

Extended mode) Control Register allows to manage all the programmable parameters

(Table 11).

The programmable functions are:

●

Channel Frequency

●

Baud Rate

●

Deviation

●

Watchdog

●

Transmission Timeout

●

Frequency Detection Time

●

Detection Method

●

Mains Interfacing Mode

●

Output Clock

●

Sensitivity Mode

●

Input Pre-Filter

In addition to these functions the Extended mode provides 24 additional bits and others

functions:

●

Output Level Freeze

●

Frame Header Recognizer (one 16 bits header of or two 8 bits headers) with support to

Frame Length Bit count
