Description
Line type array programming address
Writing to this address initiates the transfer of the data previously
written into locations 83 through 85 into an internal register array.
Line pattern array programming data
13:4 = first duration 3:0 = first select, 2:0 = first value index
...
55:46 = last duration 45 = last select, 44:42 = last value index
Line pattern array programming address
Writing to this address initiates the transfer of the data previously
written into locations 87 through 8D into an internal register array.
GPIO input enable 4
GPIO input enable 3
GPIO input enable 2
GPIO input enable 1
Output enable (Active Low)
Write to register sets the GPIO pin if output select is set to 2’b11.
Read to register returns the status of the GPIO pin if GPIO_IN_EN4
is set, otherwise it returns 0.
Output selection bits
00 = Selects gpio_out1
01 = Selects gpio_out2
10 = Selects gpio_out3
11 = Selects gpio_out4.
0 = 8-bit mode
1 =10-bit mode
0 = Incoming data stream contains a single D1 stream.
1 = Incoming data stream is in sliced mode.
De-slicer control determines where the extracted slice goes.
0:
incoming slice 1 == outgoing slice 1
incoming slice 2 == outgoing slice 2
1:
incoming slice 1 == outgoing slice 2
incoming slice 2 == outgoing slice 1
