Description
I2C Slave Address Register 3. Contains the 7-bit slave address for
operation of the I
mode. The least significant bit determines whether a slave responds to
the General Call address.
Data buffer register. The contents of the 8 MSBs of the I2DAT shift
register will be transferred to the DATA_BUFFER automatically after
every nine bits (8 bits of data plus ACK or NACK) has been received on
the bus.
I2C Slave address mask register 0. This mask register is associated
with I2ADR0 to determine an address match. The mask register has no
effect when comparing to the General Call address (‘0000000’).
I2C Slave address mask register 1. This mask register is associated
with I2ADR0 to determine an address match. The mask register has no
effect when comparing to the General Call address (‘0000000’).
I2C Slave address mask register 2. This mask register is associated
with I2ADR0 to determine an address match. The mask register has no
effect when comparing to the General Call address (‘0000000’).
I2C Slave address mask register 3. This mask register is associated
with I2ADR0 to determine an address match. The mask register has no
effect when comparing to the General Call address (‘0000000’).
