NOTE:
Access to the SRAM is not restricted in any way. The array can be
accessed in supervisor and user modes.
The MMC2113 may contain more than 8K of internal SRAM, but only the
8K range from 0x0080_0000 to 0x0080_1fff is tested and guaranteed to
be operational. It is recommended that internal SRAM outside this range
not be used. Accesses to SRAM outside this range terminate without a
transfer error exception.
In wait, doze, and stop modes, clocks to the SRAM are disabled. No
recovery time is required when exiting these modes.
