NOTES:
37. There is also a complex output mode available for 4-ch summers 1 and 3 when the cascade feature is not required. This is accomplished by
38. The cascade input of the first device in a cascade chain must be disabled.

setting the output mode to 0x01 in the top control register and selecting the complex output mode in the main control register of channel 0 or
channel 2. This mode allows I and Q data to be clocked out in parallel at the full rate. Refer to the Main Control register for further detail.

FUNCTION
39
Sync out polarity
Enables data out of the device. Zeroes the data when low.
Delays the 4 Ch sum to align with the cascade input summer. A cascade of 4 devices is supported.
Enables all four channels to receive current µP write access.
0 = defines a sync assertion as a transition from a logic low to a logic high.
1 = defines a sync assertion as a transition from a logic high to a logic low.
Indicates when I data is output in the muxed I/Q mode.
I strobe polarity.
0 = defines a sync assertion as a transition from a logic low to a logic high. (I out when low)
1 = defines a sync assertion as a transition from a logic high to a logic low. (I out when high)
Enables I and Q cascade data into the device. Zeroes the input buses when low. Set to zero when using
any mode other than Cascade.
00 = No Delay for master.
01 = Delay for first slave.
10 = Delay for second slave.
11 = Delay for last slave.
