8 General-Purpose I/O
8.1 GPIO Control Registers
8.1.2 GPIO Read Mask Register
The GPIO read mask register controls the masking of any GP signals being used as general-purpose register bits
on a read access to the GPIO register.
Table 67. GPIO Read Mask Register
8.1.3 GPIO R/W Register
The GPIO R/W register provides direction control for any of the GP signals being used as general-purpose register
bits.
