Please follow below steps:
- Power on the system.
- Wait for a period of 2ms after power supply becomes stable.
- Send 01H (LSB first) with Start bit ‘0’ and stop bit ‘1’, at the baud rate you require, this will initiate baud- rate synchronization.

4. Send 4- bit Address as “1000” (LSB first) followed by 4-bit Data as “1111” (send LSB first)
This will set the IRSP as 1111 – F8H. (check table 14,17 in datasheet)
5.Send 4- bit Address as “1001”(LSBfirst) followed by 4-bit Data as “0101”(LSBfirst).
this will set the CRIL as 5H(0101).
6. Check for the start bit, after which you should be able to receive the CA (hex).
