R/W* Slave Address Received
Indicates that the slave has recognized its own
address on the bus (defined by the contents of
the slave address register). If the general call
acknowledgement enable bit is enabled in the
slave control register, then this status bit is
also set to 1 even if the address on the bus is
a general call address. In this case, the GCAR
bit in this register is used to determine whether
or not the address is a general call address.
The STM bit indicates whether the access is
read (high) or write (low). This status becomes
active after the falling edge of SCL during the
last address bit. The slave holds SCL low
during the start of the ACK phase until the
software resets this status bit.
Note: * This bit can be read from or written to. Writing 0 clears this bit to 0 and writing 1 is
ignored.
