Notes:
43. CE
44. CNTINT is always driven.
45. CNTINC goes LOW as the counter address masked portion is incremented from xx7Fh to xx00h. The “x” is “Don’t Care.”
46. CE
47. Address “FFFE” is the mailbox location for Port 2.
48. Port 1 is configured for Write operation, and Port 2 is configured for Read operation.
49. Port 1 and Port 2 are used for simplicity. All four ports can write to or read from any mailbox.
50. 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.
