If on the PCD7.D231 and PCD7.D232 key repetition is enabled the key code trans-
mission can be repeated holding the key for a longer time.
The first repetition occurs after 0.7 Sec.
The following repetitions occur at 8 repetitions / second rate.
Above this a secondary auto-repeat started indication (0x30) may be sent.
If enabled this is sent after App. 3 Sec.
The joining auto-repeat indication off (0x31) is sent at button release.
The same indication is sent by the PCD7.D230 if the rotary wheel is turned continu-
ously in one direction (turn long).
This indication is used by the HMI to switch the decimal entry position of data for
faster entry.
This second indication and the auto-repeat can be switched on and off independent
of each other, and the auto-repeat can be set on all keys or on cursor keys only by
advanced commands.

0xb1
Run time error
indication:
Unexpected com-
mand / range error.
Command will be
ignored.
Supervisory signal:
send as response on errone-
ous commands
. Otherwise direct mode commands go
unacknowledged.
Note: In no RAM mode this also will be send as re-
sponse to commands that are normally supported but
in the no RAM case not.
0xb2
Run time error
indication:
HW LCD access
error
Supervisory signal:
one time generated (first error
only) or continuously using the repeat error off /on
command.
This error may flood the serial interface at startup so
repetition is de-active by default.
0xb3
Run time error
indication:
HW serial send
overflow
Supervisory signal:
may be generated at multiple
error reporting if one of the error messages is lost or
indicates preceding CTS blocking.
Check the CTS setting if this happens at normal use.
0xb4
Run time error
indication:
HW serial receive
overflow
Supervisory signal:
If the RTS is ignored the buffer
may overflow with the arriving data and then this sig-
nal is sent.
Correct display working is not guaranteed in this case.
