6.1.4 Go Command. Register 27 (R/W)
B7-1:
Reserved - not used.
B0:
GO
High = release reset state to start signal capture, automatically reset to zero.
Low = no action.
If this register is read, it will return zero.
6.1.5 QPSK Interrupt Output Enable. Registers 28 - 30 (R/W)
When the bits of these three registers are set high, they enable an event to generate an interrupt on the IRQ
pin 57. All interrupts may be enabled together. These registers do not affect the indication of events in the read
registers 0 - 3.
B7:
High = Enable QPSK CT LOCK indication on interrupt pin.
B6:
High = Enable QPSK CT UNLOCK indication on interrupt pin.
B5:
High = Enable QPSK LOCK indication on interrupt pin.
B4:
High = Enable QPSK UNLOCK indication on interrupt pin.
B3:
High = Enable QPSK TS LOCK indication on interrupt pin.
B2:
High = Enable QPSK TS UNLOCK indication on interrupt pin.
B1:
High = Enable QPSK CS LOCK indication on interrupt pin
B0:
High = Enable QPSK CS UNLOCK indication on interrupt pin.
B7:
High = Enable QPSK FE AGC LOCK indication on interrupt pin.
B6:
High = Enable QPSK TS AGC LOCK indication on interrupt pin.
B5:
High = Enable QPSK TS AGC UNLOCK indication on interrupt pin.
