26.1 Introduction
The keypad interface has the following features:
If the system does not use a keyboard, the Row[7:0] and Column[7:0] pins can be remapped
to General Purpose Input/Output (GPIO) pins. For details, see
page 5-25
A block diagram for the key array scanning circuitry is shown in
Note: This chapter applies only to the EP9307, EP9312, and EP9315 processors.
• A maximum 8x8 array of normally open, single pole contacts
• A back drive feature to minimize capacitance effects
• A typical scan count limit of 3 consecutive scans
• A maximum mechanical bounce time for a key press of 20 milliseconds
• A typical interrupt interval between 24 and 44 milliseconds
• A low-power wakeup mode
• A three-key reset
