Converting INT to Bit Array

INT_TO_BITARR(_E)
RnPCPU RnPCPU
RnCPU RnENCPU
(Process) (Redundant)
These functions output the lower n bits of the INT data type value to the bit array.

Setting data
■Description, type, data type
Argument Description
EN Execution condition (TRUE: Executed, FALSE: Not executed)
s Input
n Number of bits (4, 8, 12, or 16)
ENO Output status (TRUE: Normal, FALSE: Abnormal or operation stop)
d Output (An element can be specified by a variable.)
Processing details
■Operation processing
• These functions output the lower (n) bits of ANY16 type data specified by (s) to (d).
• The output bits beyond the specified number of bits are not changed.
■Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
There is no operation error.
