Hi,
Have you tested masking the ~(1<<3) to 8-bits ? It's possible that the
assembler sees a 32-bit constant where only an 8-bit value is allowed.

Hello,
I've written a PRU program which manipulates bits in one of the
registers. The program does not compile with PASM when I use the ~
operator.
Setting multiple bits works:
or r3.b0, r3.b0, 1<<3// Set bit 3
but clearing multiple bits does not:
and r3.b0, r3.b0, ~(1<<3)// Clear bit 3
The exact compiler error is " Error: Syntax error in parameter 3".
This should work since it comes straight from the TI wiki on the
PRU: http://processors.wiki.ti.com/index.php/PRU_Assembly_Instructions#Bitwise_AND_.28AND.29
Is this a bug or am I doing something wrong?
Thanks,
Michael
