TWI Device Address
The TWI device address is selected with the ADDR address select pin of the AT88RF1354.
Figure C-2. TWI Device Address
The AT88RF1354 device requires an 8-bit device address word following a start condition to enable the chip for a read
or write operation. The device address word consists of a 7 bit address followed by a read/write select bit. The write bit
should be set when sending command packets to AT88RF1354. The read bit should be set when retrieving response
packets from AT88RF1354.
Upon a successful compare of the device address, the AT88RF1354 will pull the SDI output low for 1 bit period,
sending a TWI ACK bit. If an address compare is unsuccessful, the device will return to an idle state and the SDA / SDI
line will remain pulled up by the external pull-up resistor, effectively sending a TWI NACK bit.
The AT88RF1354 ignores TWI communication packets that do not begin with a matching device address. This allows
other TWI devices to share the bus with the AT88RF1354 reader IC.
