Logical Device 7 (GPIO) Configuration
Table 24 lists the configuration registers which affect the GPIO. Only the last three registers (F0h - F2h) are described here.
See Sections 2.2.3 and 2.2.4 for a detailed description of the others.
Table 24. GPIO Conguration Register
Figure 6 shows the organization of these registers.
