As an example, to set bit B0 of the system summary 4 enable register, set
status.system4.enable = status.system4.enable.EXT.
In addition to the above constants, enableRegister can be set to the decimal value of the bit to
set. To set more than one bit of the register, set enableRegister to the sum of their decimal
values. For example, to set bits B11 and B14, set enableRegister to 18,432 (which is the sum of
2,048 + 16,384).
