4.1.1.29 Event 2 _X and _Y Registers
Some of these register bits directly reflect the status of some chip input lines, so their value depends on those
lines.

Note: Some of the bits in this register are directly forced by the hardware. Even if they are Read/Write, when the microprocessor writes
a value different from the current bit content, the hardware will immediately overwrite the microprocessor value.
