// How to Write and Read register of PCAL6416A on 16-bit GPIO Daughter card OM13489, and GPIO target  OM13303
// Set address ON OM13489: JP1 = 1&2 which is 0x42 address in Fm+ board; VDDI = VDDP = 3.3V
// Write format: |S|Addr + W|A|register pointer|A|Data1|A|Data2|A|P|
// Read format:  |S|Addr + W|A|register pointer|A|SR|Addr + R|A|Data1|A|Data2|NACK|P|
