IBT (Immediate Byte Transfer) is a Super FX instruction that loads an immediate byte into the low byte of a specified general register. The register's upper eight bits will be sign-extended (copied) from bit 7, effectively loading a signed 8-bit value.

The ALT0 state is restored.

Syntax

IBT Rn, #pp

where pp may be from -128 to 127. Any of the 16 general registers can be specified.
