When you assert VCPTAB_UPD_FORCE, the source forces the VC payload table contained in DPTX_MST_VCPTAB0 through DPTX_MST_VCPTAB7 to be taken immediately into use. No ACT sequence is generated in this case.
When you assert VCPTAB_UPD_REQ, the source requests to generate an ACT sequence and after that, use the VC payload table contained in DPTX_MST_VCPTAB0 through DPTX_MST_VCPTAB7.
