7-7 MCU_WRITE R/W 0h
AHB sets this bit to '1' to initiate frame write. This bit will be
cleared by the MCU after the write is complete.
When this register is used for eye diagram data, access is
read only and the value depends on the data written to the
register. The entire register [15:0] holds the eye diagram data.
6-6 MCU_START R/W 0h
AHB sets this bit to '1' to tell MCU to start execution.
When this register is used for eye diagram data, access is
read only and the value depends on the data written to the
register.
5-5 CHKSUM_ERR R 0h
MCU sets this bit to indicate a checksum error has occurred.
When this register is used for eye diagram data, access is
read only and the value depends on the data written to the
