6.4. PROM programming at 200 MHz fails
The board's boot PROM cannot be programmed at 200 MHz with GRMON2. It is recommended to program
the boot PROM using a system frequency no higher than 150 MHz. It is also possible to program the PROM
at a system frequency of 200 MHz by using byte or half-word accesses (depending on if the PROM is 8- or
16-bit) so that the memory controller does not convert incoming accesses into series smaller accesses.
The PROM can be read (the system can boot from PROM) at 200 MHz.
