They are updated every frame (which means the\nbank select register is cycled 60 times a second), but by default you have to\nlatch the registers manually.\n\nSELECT toggles between writing values and latching the registers (indicated by\nthe arrow on the left).\n\nWhen writing values:\n\n - UP/DOWN to change the value\n - LEFT/RIGHT to change the address and the digit you're modifying\n - A to write the byte\n\nWhen latching:\n\n - LEFT to write a 0\n - RIGHT to write a 1\n - START to switch to automatic latching. It will get disabled once you press\n   LEFT or RIGHT again.\n\nThe value last written to the latch register is highlighted.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeithecatte%2Fmbc3-fiddle","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmeithecatte%2Fmbc3-fiddle","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmeithecatte%2Fmbc3-fiddle/lists"}
