10.1 Keyboard Connection
The keyboard is connected to the chip using:
KBR (5
:0) input pins for row lines
KBC (5
:0) output pins for column lines
Figure 10-1 shows the keyboard connection.
Figure 10-1. Keyboard Connection
When a key button of the keyboard matrix is pressed, the corresponding row and column lines are shorted
together. To allow key press detection, all input pins (KBR) are pulled up to VCC and all output pins (KBC)
are driven to a low level.
Any action on a button generates an interrupt to the sequencer.
The decoding sequence is written to allow detection of simultaneous press actions on several key buttons.
The keyboard interface can be used with a smaller keyboard area than 6
× 6. To use a 3 × 3 keyboard,
KBR(4) and KBR(5) must be tied high to prevent any scanning process distribution.
