* <br><b>General Call Handling</b><br>
* Slave can receive data from master using general call address (0x00). General call

* - Call Chip_I2C_SlaveSetup() with argument @a sid as I2C_SLAVE_GENERAL
* - xfer->slaveAddr ignored, argument @a addrMask ignored
* - function provided by @a event will registered to be called when slave received data using addr 0x00
* - xfer->rxBuff and xfer->rxSz should be valid in argument @a xfer
* - To handle General Call only (No other slaves are configured)
* - Call Chip_I2C_SlaveSetup() with sid as I2C_SLAVE_X (X=0,1,2,3)
* - setup @a xfer with slaveAddr member set to 0, @a event is ignored hence can be NULL
* - provide @a addrMask (typically 0, if not you better be knowing what you are doing)
* - To handler General Call when other slave is active
* - Call Chip_I2C_SlaveSetup() with sid as I2C_SLAVE_X (X=0,1,2,3)
* - setup @a xfer with slaveAddr member set to 7-Bit Slave address [from Bit1 to 7]
* - Set Bit0 of @a xfer->slaveAddr as 1
* - Provide appropriate @a addrMask
* - Argument @a event must point to function, that handles events from actual slaveAddress and not the GC
* @warning
* If the slave has only one byte in its txBuff, once that byte is transfered to master the event handler
* will be called for event #I2C_EVENT_DONE. If the master attempts to read more bytes in the same transfer
* then the slave hardware will send 0xFF to master till the end of transfer, event handler will not be
* called to notify this. For more info see section below<br>
* <br><b> Last data handling in slave </b><br>
* If the user wants to implement a slave which will read a byte from a specific location over and over
* again whenever master reads the slave. If the user initializes the xfer->txBuff as the location to read
* the byte from and xfer->txSz as 1, then say, if master reads one byte; slave will send the byte read from
* xfer->txBuff and will call the event handler with #I2C_EVENT_DONE. If the master attempts to read another
* byte instead of sending the byte read from xfer->txBuff the slave hardware will send 0xFF and no event will
* occur. To handle this issue, slave should set xfer->txSz to 2, in which case when master reads the byte
* event handler will be called with #I2C_EVENT_SLAVE_TX, in which the slave implementation can reset the buffer
* and size back to original location (i.e, xfer->txBuff--, xfer->txSz++), if the master reads another byte
* in the same transfer, byte read from xfer->txBuff will be sent and #I2C_EVENT_SLAVE_TX will be called again, and
