SELECTING MATRIX
SH2165 BUILT-IN KEYBOARD MATRIX
The SH2165 attempts to read from
the EEPROM at offset 0x0FC0,
expecting to find the value 0xAA.
If this value is found there, the
SH2165 uses the keyboard matrix
from the EEPROM.
If this value is not found for any
reason (because there is a different
value there, or because the
EEPROM is absent or disabled),
the SH2165 uses the built-in matrix
shown at right (stored in the
SH2165 ROM).
This table shows the key values for
the populated row-column
combinations in the built-in matrix
for each of the four cases:
1. Num lock not set and function
key up
2. Num lock set and function key
up
3. Num lock not set and function
key down
4. Num lock set and function key
down
The built-in matrix includes five
custom macro keys, defined as
follows:
CUSTKEY0
= LSHIFT + F1 + ALERT
CUSTKEY1 = LSHIFT + F2
CUSTKEY2 = LSHIFT + F3
CUSTKEY3 = LSHIFT + F4
LOGON
= LCTRL + LALT + DELETE
