As an example, to set bit B0 of the service request enable register, set status.request_enable =
status.MSB.
In addition to the above values, requestSRQEnableRegister can be set to the numeric equivalent
of the bit to set. To set more than one bit of the register, set requestSRQEnableRegister to the
sum of their decimal weights. For example, to set bits B0 and B7, set
requestSRQEnableRegister to 129 (1 + 128).
