7 Basic Instructions
7.2 Connection Instructions
ANDP,ANDF
 ANDP is a rising edge pulse series connection instruction, and ANDF is a falling edge pulse series connection instruction.
They perform an AND operation with the operation result to that point, and take the resulting value as the operation result.
The ON/OFF data used by ANDP and ANDF are indicated in the table below:
Devices designated by ANDP
Bit designation of

OFF -> ON 0 -> 1
OFF 0
ON 1
ON -> OFF 1 -> 0
ORP,ORF
 ORP is a rising edge pulse parallel connection instruction, and ORF is a falling edge pulse parallel connection instruction.
They perform an OR operation with the operation result to that point and take the resulting value as the operation result.

 Arithmetic errors
 There are no arithmetic errors with LDP, LDF, ANDP, ANDF, ORP, or ORF instructions.
 Program example
 The following program executes the MOV instruction at input X0, or at the rising edge of b10 (bit10) of data register D0.
X0
0
D0. A *
6
[Remark]
 Designate the bit of the word devices in hexadecimal. Bit b10 of D0 would be D0.A.
