Terminal Functions

† 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 VC348 device. For the VC338 device only, the HET[28] signal is only connected to the pad not to a package pin.

These devices have both the logic and registers for a full 32-I/O HET

implemented, even though not 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[22:0] are high-resolution pins and HET[31:29, 24] are standard-

resolution pins for VC338x.

HET[21:18, 13:10, 8, 7, 6, 4, 2, 0] are high-resolution pins and HET[31,

24] are standard-resolution pins for VC348x.

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 (HET) Reference Guide (literature number SPNU199).

The HET[19] or HET[18] pins can also be used as a user-selectable event

source to "event trigger" the MibADC event group or group1 providing the

associated register source bits are properly configured and defined. For

the internal device connections, see the MibADC section of this data

sheet. And for more detailed functional information on the MibADC, see

the TMS470R1x Multi-Buffered Analog-to-Digital Converter (MibADC)

Reference Guide (literature number SPNU206).
