I was investigating the use of the second CPU. The MP2520F Manual states that bit 0 (A940TCLK) in the SYSCLKENREG register is set to 1 at system reset and that if it is set to 1 the second CPU is unused.
I read the value from the register with a program and it was initially 0. I also followed Dzz's Gp2x Demo Development threat and there he sets the bit to 0 to pause the second CPU and then to 1 to start it again. This is the opposite of what the documentation states.
So is this an error in the documentation? Do you guys know of more such errors? It would be helpfull to collect all such errors as an errata maybe in a page in the wiki. What do you think?
