the entire cycle. If t_CWD >= t_CWD (min), t_RWD >= t_RWD (min), T_CPWD>= T_CPWD(min), then the cycle is a read-modify-write
cycle and the data output will contain the data read from the selected address. If neither of the above conditions is
satisfied, the condition of the data out is indeterminate.
8. Either tRCH or tRRH must be satisfied for a read cycles.
9. These parameters are referenced to /CAS falling edge in early write cycles and to /WE falling edge in /OE controlled
write cycle and read-modify-write cycles.
10. Operation with the t_RAD (max) limit insures that t_RAC (max) can be met, t_RAD (max) is specified as a reference point only,
if t_RAD is greater than the specified t_RAD (max) limit, then access time is controlled exclusively by t_AA.
11. t_ASC, t_CAH are are referenced to the earlier /CAS falling edge.
12. t_CP is specified from the later /CAS rising edge in the previous cycle to the earlier /CAS falling edge in the next cycle.
13. t_CWD is referenced to the later /CAS falling edge at word read-modify-write cycle.
14. t_CWL is specified from /WE falling edge to the earlier /CAS rising edge .
15. t_CSR is referenced to the earlier /CAS falling edge before /RAS transition low.
16. t_CHR is referenced to the later /CAS rising edge after /RAS transition low.
