ms_inf_cks_err_raw, IO, Address 0x88[7] (Read Only)
This readback indicates the status of the MPEG source InfoFrame checksum error interrupt signal. When set to 1, it indicates that a
checksum error was detected for an MPEG source InfoFrame. Once set, this bit remains high until it is cleared via ms_inf_ck_clr.

vs_inf_cks_err_raw, IO, Address 0x8D[0] (Read Only)
This readback indicates the status of the vendor specific InfoFrame checksum error interrupt signal. When set to 1, it indicates that a
checksum error was detected for a vendor specific InfoFrame. Once set, this bit remains high until it is cleared.
