| ) |
Transaction: Read 1 (ONE) byte from I2C slave at address u8_addr, and save to variable u8_d1 As per the I2C standard, a NAK is returned for the last byte read from the slave, ACKs are returned for the other bytes.
| u8_addr | Slave I2C address |
| u8_d1 | variable to hold the read byte |

| u8_d1, | |||
| u8_d2 | |||
| ) |
Transaction: Read 2 (TWO) bytes from I2C slave at address u8_addr, save to variables u8_d1 and u8_d2 As per the I2C standard, a NAK is returned for the last byte read from the slave, ACKs are returned for the other bytes.
