GPIOPDATA2 - GPIO Data Register 2
Table 65. GPIOPDATA2 - GPIO Data Register 2
Register - Name
Address
Type
Register Function
This register is used for data input/output of KPY[11:8], PWM[2:0], EXTIO.
Every data I/O is masked with the associated MASK register.
If one of the I/Os is defined as output (see Table 68) values written to this
GPIODATA2
0xC4
R/W
register are masked with MASK and then applied to the associated pin.
If one of the I/Os is defined as input (see Table 68) values read from this
register hold the masked input value of the associated pin.
