6.6.7 Write to SC18IS600/601 internal registers
6.6.8 Read from SC18IS600/601 internal register
A Write Register function is initiated by sending a 0x20 command followed by an internal
register address to be written (see
address. Only one register can be accessed in a single transaction. There is no
auto-incrementing of the register address.
A Read Register function is initiated by sending a 0x21 command followed by an internal
register address to be read (see
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.
