1 Input FIFO overflow error disabled
62–63 — Reserved
14.4.2.9 MDEU ICV Size Register
The MDEU ICV size register, shown in
compared if the MDEU performs ICV comparison (see Section 14.4.2.1 "MDEU Mode Register
(MDEUMR)").
The MDEU ICV size register is cleared when the MDEU is reset or re-initialized.
