Register 0x584: RAPI Device Base Address Register
The Device Base Address Register is used to configure the address space occupied by the
FREEDM 84A1024L device for device selection.
DBADDR[3:0]
The Device Base Address bits (DBADDR[3:0]) configure the address space occupied by the
FREEDM 84A1024L device for purposes of responding to receive polling and receive device
selection. During polling in Level-2 APPI, the DBADDR[3:0] bits are used to respond to
polling via the RXADDR[3:0] pins. Polling is not used in Level-3 APPI. During device
selection, the DBADDR[3:0] bits are used to select a FREEDM 84A1024L device, enabling
it to output data on the receive APPI.
