The PPI system consists of one base for each programmer, and
exchangeable adapters. These PPI adapters accept a variety of device
package types and pin configurations. The following figures show three
common device packages and the proper device orientation in the
adapter. Each adapter has an ICON showing the proper device
orientation.
There are two different pinouts for the TSOP device as shown in Figure
A-18. The standard pinout, shown by the standard pinout ICON on the

ICON on the right in Figure A-18, shows Pin 1 indicated by a triangle in
the upper-left corner of the device.
