Examples When the key code associated with key 'P' (0x50) is pressed, the release
code is 'p' (0x70). In RS-232 polled mode or via the I2C, the “Key
Down / Key Up” codes are used; however, the user should be careful of
timing details. If the poll rate is slower than the simulated
auto-repeat it
is possible that polling for a key up code will be delayed long
enough
for an unwanted key repeat to be generated.

Decimal 254 213 [KDown] [KUp]
Parameters
Parameter Length Description
KDown 25 Key down codes
KUp 25 Key up codes
Description This command will allow you to reassign the key codes that correspond
to the key presses on the matrix style key pad. The ?rst 25 byte
s that are
transmitted will be used for the key down codes and the next 25
bytes
that are transmitted will be used for the key up codes.
