h) EYECLK, EYEDAT
Eye pattern monitor connection pins
i) ABITCLK, BBITCLK
Serial data clocks
ASPCLK, BSPCLK
Serial data synchronization signals
ATXD, BTXD
Transmitted serial data (MN195007 => AFE direction）
ARXD, BRXD
Received serial data (MN195007 => AFE direction）
These AFE interface pins are divided into two channels: A and B.
The first letter (A or B) heading each signal name identifies the channel name.
The pin direction switches according to the AFE type set by GPIO [4] and [5].

Note: If a pin is out of use, be sure to carry out free pin handling as specified in [ Table 5 ].
Because ATXD and BTXD enter a high-impedance state when the output pin is reset,
be sure to pull them down to finalize the level.
j) AFESEL[0], AFSEL[1]

Set pins depend of connecting AFE type as shown in [ Table 6 ]
