The B768 device has both the logic and registers for a full 32-I/O HET
implemented and all 32 pins are available externally.
Timer input capture or output compare. The HET[31:0] applicable pins can be
programmed as general-purpose input/output (GIO) pins. HET[23:0] are
high-resolution pins and HET[31:24] are standard-resolution pins.
The high-resolution (HR) SHARE feature allows even HR pins to share the
next higher odd-numbered 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 (HET) 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.)
