Does PicoBlaze have separate flags for each regbank (like Z80), or are the same flags used in both regbanks? For instance, consider the following code:
regbank a
load s0, 0
sub s0, 0
regbank b
load s0, 1
sub s0, 0
regbank a
jump z , success
jump nz, failure
Where will it jump? To success or to failure?
In my PicoBlaze Simulator (it's runnable in a browser, try the "Regbanks-Flags Test" example, the 7th example from the left), it jumps to success. But I am not sure what it would do on real PicoBlaze.
