Instruction
Type Read/Write.
Function The function bits select the desired register operation in either
the target or initiator role.
101 - Move the SFBR register to the specified destination
register
110 - Move the specified register to the SFBR register
111 - Read a specified register, modify it, and write the result
back into the same register
Operator Specifies which logical or arithmetic operation will be
performed.
000 - Move, no modification performed
001
1
- Shift source left one bit, store result in destination
010 - OR immediate data with source, store result in
destination
011 - XOR immediate data with source, store result in
destination
100 - AND immediate data with source, store result in
destination
101
1
- Shift source right one bit, store result in destination
110 - ADD immediate data to source, store result in destination
111 - Add in immediate data plus Carry bit to source; store
result in destination
1. Data is shifted through the Carry bit and the Carry bit is shifted into the data
byte.
