General Call Address Support
S
The addressing procedure for the I
usually determines which device will be the slave addressed by the master. The exception is the
general call address which can address all devices. When this address is used, all devices
should, in theory, respond with an acknowledge.
The general call address is one of eight addresses reserved for specific purposes by the I
tocol. It consists of all 0’s with R/W = 0.
The general call address is recognized when the General Call Enable bit (GCEN) is enabled
(SSPCON2<7> set). Following a start-bit detect, 8-bits are shifted into SSPSR and the address
is compared against SSPADD, and is also compared to the general call address, fixed in hard-
ware.
If the general call address matches, the SSPSR is transferred to the SSPBUF, the BF flag bit is
set (eight bit), and on the falling edge of the ninth bit (ACK bit) the SSPIF interrupt flag bit is set.
When the interrupt is serviced. The source for the interrupt can be checked by reading the con-
tents of the SSPBUF to determine if the address was device specific or a general call address.
In 10-bit mode, the SSPADD is required to be updated for the second half of the address to
match, and the UA bit is set (SSPSTAT<1>). If the general call address is sampled when the
GCEN bit is set while the slave is configured in 10-bit address mode, then the second half of the
address is not necessary, the UA bit will not be set, and the slave will begin receiving data after
the acknowledge
