File Registers (FL)

Function of file registers (FL)
File registers are memory areas which are handled in word (16−bit) units, and are used
to store data such as numerical data configured of 16 bits.
They can be used in exactly the same way as data registers.

Double−word specifications can also be used in the same way as with data registers.
32−bit data can be handled.
The number of file registers varies depending on the type and the system register
settings.

Note
The number of words varies depending on the type and the
system register settings.
Non−hold type data and hold type data
System register 9 can be used to specify whether hold types or non−hold types of file
registers are to be used. For the default setting, all file registers are hold types.
For the FP2/FP2SH/FP10SH, if the Initialize/Test switch is set to the upper side (the
Initialize side) in the PROG mode, all file registers are cleared to 0. Even if a hold type
has been specified, these are cleared to 0.
Note
With the FP2SH/FP10SH, system register 4 can be set in such a way
that the file registers are not cleared to 0 even if the Initialize/Test
switch is set to the upper side.
