Notes:
1.
These timings apply to the B4 version of the élanSC300 microcontroller only. The timings for the B3 version are t5b = 260,
t6b = 0, t12b = -2 ns, and t14 = -4 ns.
These timings are based on default settings and required initial programming. These timings may be modified via the MMS
Memory Wait State1 Register, Index 62h, and the Command Delay Register, Index 60h. (See theélan
