Section 2 Instruction Descriptions
SUB (SUBtract binary)
Notes
The SUB.B instruction can operate only on general registers. Immediate data can be subtracted
from general register contents by using the SUBX instruction. Before executing SUBX #xx:8, Rd,
first set the Z flag to 1 and clear the C flag to 0. The following coding examples can also be used
to subtract nonzero immediate data #IMM.
(1) ORC
(2) ADD
