This register provides for control of the nominal APC setpoint and management of interrupts by the end-user. APCSEL[1:0]
select which of the APC setpoint registers, APCSET0, APCSET1, or APCSET2 are used as the nominal automatic power
control setpoint. Similarly, MODSEL[1:0] select which of MODSET0, MODSET1, or MODSET2 are used to select the
modulation level of the laser.
IE must be set for any host interrupts to occur via the /INT pin. If IE is set while /INT is asserted, /INT will be deasserted
immediately.
PORS is always set high by any power-on reset event. If PORM is high, the power-on event will also generate a host interrupt.
PORS will be cleared to zero and the interrupt output deasserted when USRCTL is read by the host.
If PORM is set following the setting of PORS, PORS will remain set, and /INT will be asserted immediately. /INT will not be
deasserted until USRCTL is read by the host.
PORM, IE, APCSEL, and MODSEL are non-volatile and will be maintained through power and reset cycles.
