OVRLOPCNT: Overall Loop Count[5:0]
0h: Send no IBIST data in payload
1h-3Fh: The number of times to loop through all the patterns
CNSTGENCNT: Constant Generator Loop Counter[4:0]
00h: Disable constant generator output
01h: 1Fh The number of times the Modulo-N counter should be repeated before
going to the next pattern type. Each buffer transfer is composed of two frames
(loop counts of 24-bits each).
CNSTGENSET: Constant Generator Setting
0: Generate 0
1: Generate 1
MODLOPCNT: Modulo-N Loop Counter
Each count represents 24-bits of the pattern specified by the MODPERIOD bit field.
00h: Disable Pattern Output
01h: 7Fh The number of times the Pattern Buffer should loop before going to the
next
MODPERIOD: Period of the Modulo-N counter

PATTLOPCNT: Pattern Buffer Loop Counter[6:0]
00h: Disable Pattern Output
01h-3Fh: The number of times the Pattern Buffer should be repeated before going
to the next pattern type. Each buffer transfer is composed of two frames (loop
counts of 24-bits each).
