1045  *     - 2 MB
1046  *     - *BCTL0 is asserted upon access to the current memory bank
1047  *     - *CW / *WE are negated a quarter of a clock earlier
1048  *     - *CS is output at the same time as the address lines
1049  *     - Uses a clock cycle length of 5
1050  *     - *PSDVAL is generated internally by the memory controller
1051  *       unless *GTA is asserted earlier externally.
1052  *     - Relaxed timing is generated by the GPCM for accesses
1053  *       initiated to this memory region.
1054  *     - One idle clock is inserted between a read access from the
1055  *       current bank and the next access.
