Pre-discharge mode is provided for applications that use 3.3-V/5-V external memories while the
MPC561/MPC563 data bus pads are optimized to 2.6-V memories, and cannot tolerate more than 3.1 V.
When connecting 3.3-V devices to the E-bus, and performing read and write operations, this mode should
be invoked in order to avoid long term reliability issues of the data pads.
When the PDMCR2[PREDIS_EN] bit is set, the MPC561/MPC563 will discharge the bus during the
address phase of any write cycle prior to the data phase. The data bus will be discharged from up to 5 V to
a level which is suitable to the low voltage drivers. In most cases, the ORx[EHTR] bit of the relevant
memory bank, should be set along with the PREDIS_EN bit in order to reserve sufficient time for the
