Number $0A
Readable Yes
Writable Yes
Short Description Used within the Anti-brick system.


Bit mapped:

Bit Effect
7 FPGA loads reflashable core (if 0, FPGA loads the fixed anti-brick core)
6-2 Reserved
1 DivMMC button pressed
0 Multiface button pressed

Note that in normal running pressing the DivMMC or Multiface button creates an NMI which halts any running program, and the reflashable core must be loaded before any user code is run. This means that unless you are rewriting the entire firmware from scratch this register is probably not useful.
