Similarly, you can connect a 32-bit packed integer to LI01 and access the bits
directly as I01-I32.
IN I01 ; read bit 1 of LI01 to the stack
IN I17 ; read bit 17 of LI01 to the stack
Only LI01 and LO01 can be accessed bit-wise, not LI02 & LO02.
If you want to do 16-bit logic (ANDX, XORX, etc), use INH & INL to read the
high & low 16-bits of of LIxx or LOxx.

John,
I think I have done something like this in the past. May not be exactly
right, but I believe the concept works.
Bring booleans in via MCOUTs into II01 and 02 on CALCA and move into
LO01. You can then perform Boolean operations on the individual bits in
LO01 (O01-O32).
Booleans 1-16 --> IN1-16[MCOUT1]PAKCRB --> II01[CALCA]
|----->LO01
Booleans 17-32 --> IN1-16N[MCOUT2]PAKCRB --> II02[CALCA]
Something Like
IN II01; B1-16 to High Bytes
STH LO01;
IN II02; B17-B32 to Low Bytes
STL LO01
|
AND L01 LO2; Do Required Boolean Logic
OR L17 L18; etc

I want to execute logic on 18 boolean values but I see the CALCA block
only has 16 boolean inputs. Can I bring a couple of booleans in as
integers? What would be the most direct way to accomplish this?
