if ((unsigned) rA > (unsigned) IMMED)
then rB ← 1
else rB ← 0
cmpgtui rB, rA, IMMED
cmpgtui r6, r7, 100
Zero-extends the immediate value IMMED to 32 bits and compares it to the value of rA. If rA >
IMMED, then cmpgtui stores 1 to rB; otherwise stores 0 to rB.
cmpgtui performs the unsigned > operation of the C programming language. The maximum
allowed value of IMMED is 65534. The minimum allowed value is 0.
cmpgtui is implemented using a cmpgeui instruction with an IMM16 immediate value of
IMMED + 1.
