SC18IS600/601
SPI to I2C-bus interface
6.6.7 Write to SC18IS600/601 internal registers
A Write Register function is initiated by sending a 0x20 command followed by an internal
register address to be written (see Section 6.1). The register data byte follows the register
address. Only one register can be accessed in a single transaction. There is no
auto-incrementing of the register address.
6.6.8 Read from SC18IS600/601 internal register
A Read Register function is initiated by sending a 0x21 command followed by an internal
register address to be read (see Section 6.1) and a dummy byte. The data byte of the
read register is returned by the SC18IS600 on the MISO pin. Only one register can be
accessed in a single transaction. There is no auto-incrementing of the register address.
Note that write and read from internal registers are processed immediately as soon as the
SC18IS600/601 determines the intended register.
