Notes:
41. Q(A
42. CE
43. Burst ends when new address and control are loaded into the SRAM by sampling ADV/LD LOW.
44. WEN is “Don’t Care” when the SRAM is bursting (ADV/LD sampled HIGH). The nature of the burst access (Read or Write) is fixed by the state of the WEN signal
45. BWc and BWd apply to 256K × 36 device only.
