6.2.6
MCR is an 8-bit readable/writable register that selects the DRAM strobe control method, number
of precharge cycles, access mode, address multiplexing shift size, and the number of wait states
inserted during refreshing, when areas 2 to 5 are designated as DRAM interface. When areas 2 to
5 are designated as PSRAM interface, MCR selects the number of precharge cycles and the access
mode for PSRAM.
