Example of indirect access register write and read operations
Address: 0x05
Register name: TWIADD, TWI device address
Example of indirect access register WRITE operation (write 0x0D to indirect register CFG, 0x00):
Example of indirect access register READ operation (read indirect register CFG, 0x00):
SCP1000 has internal non-volatile memory for calibration and configuration data. Memory content
will be programmed during production. Initial configuration is loaded during sensor start-up.
EEPROM register contents and bit definitions are described in this section. User has access to 4
EEPROM registers. EEPROM registers can be accessed through the serial interface using the
OPERATION, DATAWR, ADDPTR and DATARD8 registers (see sections 3.4.1 and 3.4.2).
