CONNECTION WITH EXTERNAL DEVICES
12.1 Signals required for accessing external devices
12–10
<8/16-bit data access>
External data bus width = 8 bits (BYTE = “H”)
Note: When accessing 16-bit data, 2 times of access are performed in
(e) Access from even address
(f) Access from odd address
the sequence of the low-order 8 bits and high-order 8 bits.
