Non−hold type data and hold−type data
There are two types of data registers which handle data differently when the power is
turned off or the mode is changed from RUN to PROG.:
− Hold type data registers hold their contents while operation stops and allow
operation to be restarted with the contents still effective.
− Non−hold type data registers reset when operation stops.
For the FP0 C10/C14/C16/C32, and FP−e without clock/calendar function, non−hold
type and hold type data register numbers are as shown in the following table.
Item
Data register Non−hold type
Hold type
For theFP0 T32C/FPΣ/FP0R/FP−X/FP2/FP2SH/FP10SH, and FP−e with
clock/calendar function, system register 8 can be used to specify whether hold types
or non−hold types are to be used. If the beginning of a hold type data register is
specified using a word number, data registers before that point will be non−hold
types, and subsequent data registers will be hold types.

Default settings for hold types and non−hold types
Type
FPΣ, FP−X (C30, C60)
FP−X (C14)
FP−e
FP0R C10, C14, C16
FP0R C32, T32, F32
Note
For FPΣ, FP−X and FP−e, in case of not using back−up battery,
please keep the default value. Otherwise we cannot guarantee
the function of hold/non−hold value.
For the FP2/FP2SH/FP10SH, if the Initialize/Test switch is set to the upper side (the
Initialize side) in the PROG mode, all data registers (DT) are cleared to 0. Even if a hold
type has been specified, these are cleared to 0.
