2.7.3.5 I²C Interface Disable

While not necessary in a well-designed implementation, the MCP16503 also supports I²C interface disabling.

This is achieved by issuing three separated Single Write commands as follows (ADDRESS equals the device address in 7-bit format, default = 0x5A):

1. ADDRESS = 0x5A, COMMAND = 0xEA, DATA = 0xBD
2. ADDRESS = 0x5A, COMMAND = 0xE9, DATA = 0xBD
3. ADDRESS = 0x5A, COMMAND = 0xEC, DATA = 0xBD

Upon ACK of the last byte, the I²C interface will no longer respond to the device address or any other bus transaction.

To enable the I²C interface again, power (SVIN) must be cycled.
