;Enable I2C slave mode
;Set the slave device address to 5A
;/That is, I2CSLADR[7:1]=010_1101B, MA=0B.
;Since MA is 0, the device address sent by the host must be
; the same as I2CSLADR[7:1] to access this I2C slave device.
;If the host needs to write data, it will send 5AH(0101_1010B)
;If the host needs to read data, it will send 5BH (0101_1011B)
