General Purpose Readable Jumpers Header (J22)
Header J22 provides eight readable jumpers. These jumpers are read as a
register (at $FFF4202D) in the MCchip LCSR (local control/status register).
The bit values are read as a zero when the jumper is installed and as a one
when the jumper is removed.
register (at $FFF4202D) in the MCchip LCSR (local control/status register).
The bit values are read as a zero when the jumper is installed and as a one
when the jumper is removed.
If the MVME162BUG firmware is installed, four jumpers are user-definable
(pins 1-2, 3-4, 5-6, 7-8). If the MVME162BUG firmware is not installed, seven
jumpers are user-definable (pins 1-2, 3- 4, 5-6, 7-8, 11-12, 13-14, 15-16).
