4.43 General-Purpose Input Register
The general-purpose input register provides the logical value of the data input from the GPI terminals, MFUNC5,
MFUNC4, and MFUNC2−MFUNC0. Access this register only through function 0. See Table 4−19 for a complete
description of the register contents.

Table 4−19. General-Purpose Input Register Description
BIT SIGNAL TYPE FUNCTION
15−5 RSVD R Reserved. Bits 15−5 return 0s when read.
4 GPI4_DATA R GPI4 data bit. The value read from bit 4 represents the logical value of the data input from the MFUNC5 terminal.
3 GPI3_DATA R GPI3 data bit. The value read from bit 3 represents the logical value of the data input from the MFUNC4 terminal.
2 GPI2_DATA R GPI2 data bit. The value read from bit 2 represents the logical value of the data input from the MFUNC2 terminal.
1 GPI1_DATA R GPI1 data bit. The value read from bit 1 represents the logical value of the data input from the MFUNC1 terminal.
0 GPI0_DATA R GPI0 data bit. The value read from bit 0 represents the logical value of the data input from the MFUNC0 terminal.
