Notes:
52. CE
= OE = ADS = CNTEN = LOW; CE
= CNTRST = MRST = CNT/MSK = HIGH.
53. Address “1FFFF” is the mailbox location for R_Port.
54. L_Port is configured for Write operation, and R_Port is configured for Read operation.
55. At least one byte enable (B0 – B3) is required to be active during interrupt operations.
56. Interrupt flag is set with respect to the rising edge of the Write clock, and is reset with respect to the rising edge of the Read clock.
57. OE is an asynchronous input signal.
58. When CE changes state, deselection and Read happen after one cycle of latency.
59. CE
0
= OE = LOW; CE
1
= R/W = HIGH.
