6.2.3 SDataOut
The SDataOut signal carries output bits associated with devices on the target. For
example, on 4138xx the SGPIO can drive up to three bits per device and up to eight
devices on the target, thus is able to control twenty-four outputs on the target. The
SDataOut signal carries the 3-bit outputs for each device in the same order in each
repeated bit stream.
6.2.4 SGPIO SDataIn Signal
The SDataIn signal carries input bits associated with devices on the target. For
example, on 4138xx the SGPIO can receive up to three bits per device and up to eight
devices on the target, thus is able to receive twenty-four inputs from the target. The
SDataIn signal carries the 3-bit inputs for each device in the same order in each
repeated bit stream.
