SwitchToClassicSFP (64H)
Command Description
The SwitchToClassicSFP (64H) command instructs the touch system to
return to the classic Smart-Frame Protocol. (Within SFP-II, the original
Smart-Frame Protocol is referred to as the “classic” SFP.) After the
associated report is returned, the touch system accepts only SFP
commands and does not accept SFP-II commands. To return to SFP-II,
the host must send the SwitchToSFP-II (65H) SFP command.
Command Format

Report Description
The Switch To Classic SFP Report reports to the host the result of the
touch system's attempt to return to the classic SFP.
