All devices have both the logic and registers for a full 32-I/O HET
implemented, even though not all 32 pins are available externally.

can be programmed as general-purpose input/output (GIO) pins.

The high-resolution (HR) SHARE feature allows even HR pins to share
the next higher odd HR pin structures. This HR sharing is independent of
whether or not the odd pin is available externally. If an odd pin is available
externally and shared, then the odd pin can only be used as a general-
purpose I/O. For more information on HR SHARE, see the TMS470R1x
High-End Timer Reference Guide (literature number SPNU199).

† I = input, O = output, PWR = power, GND = ground, REF = reference voltage, NC = no connect
‡ All I/O pins, except RST, are configured as inputs while PORRST is low and immediately after PORRST goes high.
§ IPD = internal pulldown, IPU = internal pullup (all internal pullups and pulldowns are active on input pins, independent of the PORRST state.)
¶ N/A on the VC346 device. For the VC336 device, the HET[28] signal is only connected to the pad, not to a package pin.
