Typical program and erase times assume nominal supply values and operation at 25
change pending device characterization.
Initial factory condition: < 100 program/erase cycles, 25
frequency.
The maximum erase time occurs after the specified number of program/erase cycles. This maximum value is
characterized but not guaranteed.
Page size is 128 bits (4 words).

APC, RWSC and WWSC are fields in the flash memory BIUCR register used to
specify wait states for address pipelining and read/write accesses. Illegal
combinations exist—all entries must be taken from the same row.
TBD: To Be Defined.
APC must be equal to RWSC.
150 MHz + 2% FM = 153 MHz.
