Simultaneous Keypress Detection
Certain applications require the detection of
simultaneous keypresses, such as <SHIFT+KEY> and
<FUNCTION+KEY> combinations. This is done in
software. For instance, the P detects the SHIFT key is
being pressed. When the P detects an additional key-
press instead of a key release, it knows the corre-
sponding code is a result of two resistors
in parallel.
Order of Keypress Detection
Some applications require detection of the specific
sequence of keys in software by looking for unique key
presses within 32 ticks (1s). If the duration between
keypresses exceeds the allowed time, assume the key-
press is in error and return to the previous known state.
Power-Up Jack Detect and Keypress
Example
Figure 10 illustrates the FIFO entries during a typical
sequence of events.
Layout, Grounding, and Bypassing
Position RSENSE and CSENSE as close to the device as
possible. Bypass VDD with a 0.1F capacitor to GND as
close to the device as possible. Connect GND to a
quiet analog ground plane. Route digital lines away
from SENSE and FORCE.
