SRAM address space is configured as one sector, the wait states are configured by the
SRW11 and SRW10 bits.
Table 2. Sector Limits with Different Settings of SRL2..0
• Bit 1 and Bit 6 MCUCR – SRW11, SRW10: Wait State Select Bits for Upper
The SRW11 and SRW10 bits control the number of wait states for the upper sector of
the External Memory address space, see Table 3.
• Bit 3..2 – SRW01, SRW00: Wait State Select Bits for Lower Sector
The SRW01 and SRW00 bits control the number of wait states for the lower sector of
the External Memory address space, see Table 3.
