Document Number: 38-06054 Rev. *D
49. Test conditions used are Load 2.
50. Timing shown is for x18 bus matching; x9 bus matching is similar with 4 cycles between address inputs.
51. See table “Right Port Operation“ for data output on first and subsequent cycles.
52. CNTEN = V
53. CE = ADS = CNTEN = V
54. During “No Operation,” data in memory at the selected address may be corrupted and should be rewritten to ensure data integrity.
55. BM, SIZE, and BE must be reconfigured 1 cycle before operation is guaranteed. BM, SIZE, and BE should remain static for any particular port configuration.
