10.2 Programming guidelines to avoid hardware failure or damage
Users must be aware of the following guidelines to avoid potential hardware failure or damage.
• Do not program the Refresh OTP and Soft Reset bits to a 1 state at the same time.
• Soft Reset bit will reset Engineering Mode (EM).
• The Soft Reset bit is easily accessible; therefore, be cautious of the accidental reset.
• Tx_EN must not be active during an OTP refresh or during Engineering Mode.
10.3 Group programming
A common way of grouping A3M36SL039 modules is with parallel data inputs and unique chip CS_B connectivity. In this case,
each module can be independently controlled and programmed by its individual CS_B, which has more flexibility to program
