Breakpoint for specific memory location/value

Chris Green

In uVision 5.10.0.2 I'm trying to set an access breakpoint on a gpio port/pin using the following but get an error.

BA ReadWrite 0x400FF100, 4, "_break_ = (_RWORD(0x400FF100) & 0x00000010)"


*** error 71: invalid expression type

I can use

BA ReadWrite 0x400FF100, 4

but don't want to break unless a specific pin has activity.
