6.4.5.3
Slave receiver mode
In the Slave Receiver mode, data bytes are received from a master transmitter. To
initialize the Slave Receiver mode, the user should write the slave address to the Slave
Address Register (S1ADR) and the I2C-bus Control Register (S1CON) should be
configured as follows:
CR2:0 are not used for slave mode. ENS1 must be set = 1 to enable I2C-bus function. AA
bit must be set = 1 to acknowledge its own slave address or the general call address.
STA, STO and SI are cleared to 0.
After S1ADR and S1CON are initialized, the interface waits until it is addressed by its own
address or general address followed by the data direction bit which is 0(W). If the direction
bit is 1(R), it will enter Slave Transmitter mode. After the address and the direction bit
have been received, the SI bit is set and a valid status code can be read from the Status
Register(S1STA). Refer to Table 25 for the status codes and actions.
6.4.5.4
Slave transmitter mode
The first byte is received and handled as in the Slave Receiver mode. However, in this
mode, the direction bit will indicate that the transfer direction is reversed. Serial data is
transmitted via P1[7]/SDA while the serial clock is input through P1[6]/SCL. START and
