lanSC310 Microcontroller Data Sheet
PREL IMINARY
Notes:
These timings may be modified via the MMS Memory Wait State 1 Register, Index 62h, and the Command Delay Register, Index
60h. (See the lanTMSC310 Microcontroller Programmer’s Reference Manual, order #20665.)
1. These timings apply only to the B4 version of the lanSC310 microcontroller. The timings for the B3 version are t2b = 0 ns,
t3b = 550 ns, t11b = -2 ns, and t13 = -4 ns.
