Section 6 Instruction Descriptions
6.1.43
Format
NEGC Rm,Rn 0 – Rm – T
Description: Subtracts general register Rm data and the T bit from 0, and stores the result in Rn.
If a borrow is generated, T bit changes accordingly. This instruction is used for inverting the sign
of a value that has more than 32 bits.
Operation:
