3.13.2 HPI Data Pins as General-Purpose I/O  
The 8-bit bidirectional data bus of the HPI can be used as general-purpose input/output (GPIO) pins when  
the HPI is disabled (HPIENA = 0) or when the HPI is used in HPI16 mode (HPI16 = 1). Two  
memory-mapped registers are used to control the GPIO function of the HPI data pins—the gen-  
eral-purpose I/O control register (GPIOCR) and the general-purpose I/O status register (GPIOSR). The  
GPIOCR is shown in Figure 3-20.

The direction bits (DIRx) are used to configure HD0-HD7 as inputs or outputs.  
The status of the GPIO pins can be monitored using the bits of the GPIOSR. The GPIOSR is shown in  
Figure 3-21.

3.14 Device ID Register  
A read-only memory-mapped register has been added to the device to allow user application software to  
identify on which device the program is being executed.
