GPI3 status. This bit is set on a change in status of the MFUNC4 terminal input level if configured as a
general-purpose input, GPI3.
2 ‡ GP2_STS RCU
GPI2 status. This bit is set on a change in status of the MFUNC2 terminal input level if configured as a
general-purpose input, GPI2.
1 ‡ GP1_STS RCU
GPI1 status. This bit is set on a change in status of the MFUNC1 terminal input level if configured as a
general-purpose input, GPI1.
0 ‡ GP0_STS RCU
GPI0 status. This bit is set on a change in status of the MFUNC0 terminal input level if configured as a
general-purpose input, GPI0.
