The core provides four interrupt priority levels among six group sources. The 73S12xxF sources are
grouped as shown in Table 3. All sources belonging to a group share the same interrupt priority level.
The LAPI sets up the four priority levels for these groups as shown in Table 3.

The low-level APIs are listed below. Additional details are in the subsequent subsections.
4.2.1
Keyboard Driver API – Available with all 73S12xxF Devices
The Keyboard Driver manages the keystroke acquisition using a scrambled algorithm. It is the High-level
API’s role to manage the scrambling algorithm. Up to 30 keys can be managed in a 6 row by 5 column
configuration. The APIs below are written to use Hardware Scan enabling. An application can be written
to bypass Hardware Scanning to perform its own manual key scan functionality. Refer to the 73S12xxF
Data Sheet for information on the keypad bypass mode.
The Keyboard Driver API includes:
