For each L3_MAIN write or read access associated with the virtual frame buffer, the OCM controller performs various address error checks to prevent illegal CBUF accesses from causing false overflow and underflow conditions. Once the L3_MAIN VBUF address is determined as valid, the OCM controller further checks for overflow and underflow conditions to properly handle the access to the CBUF during each one of these conditions and to notify for error condition an external host.
For more information regarding all CBUF events see, Table 15-556, OCM Subsystem Events.
