USRCID - User Source Address
Volatile Address = 0x5E-0x61; Non-Volatile Address = 0x13-0x16
These registers contain the address of the module when User Addressing
mode or Extended User Addressing mode are enabled. User Addressing
mode uses bytes 0 and 1 to determine the source address for both
transmitted messages and matching received messages. Extended User
Addressing mode uses all four bytes. When the COMPAT register is 0x02 in
User Address mode, bytes 3 and 2 must be 0. Please see the Addressing
Modes section for more details. Each register byte is read and written
separately. Figure 65 shows the User Source ID registers.
UDESTID - User Destination Address
Volatile Address = 0x5A-0x5D; Non-Volatile Address = 0x0F-0x12
These registers contain the address of the destination module when User
Addressing mode or Extended User Addressing mode are enabled. User
Addressing mode uses bytes 0 and 1 to determine the destination address.
Extended User Addressing mode uses all four bytes. These registers are
automatically filled with the source address from a received message if the
received message address type matches the value in AUTOADDR. Please
see the Addressing Modes section for more details. Each register byte
is read and written separately. Figure 64 shows the User Destination ID
registers.
