F5H
Default disable
The Default Disable command resets all condi-
tions to the power on default states. The
HT82K628A will respond with ACK, clears its
output buffer, sets the default key types (scan
code set 3 operation only) and typematic
rate/delay, and clears the last typematic key.
The HT82K628A then stops scanning and
awaits further command.
F6H
Set default
The Set Default command resets all conditions
to the power on default states. The HT82K628A
will respond with ACK, clears its output buffer,
sets the default key types (scan code set 3 oper-
ation only) and typematic rate/delay, and clears
thelasttypematickeythencontinuesscanning.
F7H, F8H, F9H, FAH
Set all keys
These commands instruct the HT82K628A to
set all keys to the type listed below:
Hex Value
Command
F7
Set All Keys-Typematic
F8
Set All Keys-Make/Break
F9
Set All Keys-Make
FA
Set All Keys-Typematic
/Make/Break
The HT82K628Awill respond with ACK, clears
its output buffer, sets all keys to the type indi-
catedbythiscommand,andcontinuesscanning
(if it was previously enabled). Although these
commands can be sent using any code set, they
affect only scan code set 3 operation.
FBH, FCH, FDH
Set key type
These commands instruct the HT82K628A to
set individual keys to the type listed below:
Hex Value
Command
FB
Set Key Type-Typematic
FC
Set Key Type-Make/Break
FD
Set Key Type-Make
The HT82K628Awill respond with ACK, clears
its output buffer and prepares to receive key
identification. Key identification is accom-
plished by the host identifying each key by its
scan code value as defined in scan code set 3.
Only scan code set 3 values are valid for key
identification. The type of each identified key is
set to the value indicated by the command.
Although these commands can be sent using
any code set, they affect only scan code set 3 op-
eration.
FEH
Resend
The host sends this command when it detects
an error in any transmission from the
HT82K628A. It is sent only after a data trans-
mission and before the host allows the next
data output. When a Resend is received, the
HT82K628A sends the previous output again
(unless the previous output was Resend, in
which case the HT82K628A sends the last byte
before the Resend command).
