nized. Otherwise, the general call address is ignored. The contents of this register are ignored when
SMBus0 is operating in master mode.
20.4.5. Status Register
The SMB0STA Status register holds an 8-bit status code indicating the current state of the SMBus0 inter-
face. There are 28 possible SMBus0 states, each with a corresponding unique status code. The five most
significant bits of the status code vary while the three least-significant bits of a valid status code are fixed at
zero when SI = ‘1’. Therefore, all possible status codes are multiples of eight. This facilitates the use of sta-
tus codes in software as an index used to branch to appropriate service routines (allowing 8 bytes of code
to service the state or jump to a more extensive service routine).

SLV6-SLV0: SMBus0 Slave Address.
These bits are loaded with the 7-bit slave address to which SMBus0 will respond when oper-
ating as a slave transmitter or slave receiver. SLV6 is the most significant bit of the address
and corresponds to the first bit of the address byte received.
GC: General Call Address Enable.
This bit is used to enable general call address (0x00) recognition.
0: General call address is ignored.
1: General call address is recognized.
