20.3.21 MC Command FIFO (MCCF)
MCCF is in the MC register block and receives commands. This register uses the FIFO method
and recognizes a maximum of eight command parameters according to the writing order. This
register does not retain the written values. This register is always read as 0.
Setting Method: When accessing this register, the MC_EN bit in GACER should be set to 1.
Access is possible only when the MC_EN bit is set to 1. If the MC_EN bit is 0, access is invalid
(writing is invalid; the read value is indefinite).
The following shows the setting contents assumed according to the writing order:
