MPF PWRITE Partial Write

MPF PWRITE (Partial Writes)

CCI-P supports only full-line reads and writes. The MPF PWRITE module, enabled by setting ENABLE_PARTIAL_WRITES, adds a vector of byte-level masks to the CCI-P channel 1 write interface. Partial writes are implemented as read-modify-write inside MPF and thus have relatively high latency. Partial writes should be avoided whenever possible. AFUs requiring MPF PWRITE often also require WRO as well.
