3.3 V
Video Port 4 Control 0 or EMIFA bank address control (ABA[1:0])
(O/Z). Active-low bank selects for the 16-bit EMIFA. When
interfacing to 16-bit asynchronous devices, ABA1 carries bit 1 of
the byte address. For an 8-bit asynchronous interface, ABA[1:0]
are used to carry bits 1 and 0 of the byte address.
Video Port 4 Control 1 or EMIFA bank address control (ABA[1:0])
(O/Z). Active-low bank selects for the 16-bit EMIFA. WHEN
interfacing to 16-bit asynchronous devices, ABA1 carries bit 1 of
the byte address. For an 8-bit asynchronous interface, ABA[1:0]
are used to carry bits 1 and 0 of the byte address.
Video Port 4 Control 2 or Programmable synchronous address
strobe or read-enable. For programmable synchronous interface,
the r_enable field in the ChipSelect x Configuration Register
selects between ASADS and ASRE:
– If r_enable = 0, then the ASADS/ASRE signal functions as the
ASADS signal.
– If r_enable = 1, then the ASADS/ASRE signal functions as the
ASRE signal.
Video Port 4 Data 2 or EMIFA byte-enable control 0. Decoded
from the low-order address bits. The number of address bits or
byte enables used depends on the width of external memory.
Byte-write enables for most types of memory.
Video Port 4 Data 3 or EMIFA byte-enable control 1. Number of
address bits or byte enables used depends on the width of
external memory. Byte-write enables for most types of memory.
