3.6.4 How to Start with an 8-Bit Data Bus
Resetting sets the CS2 pin low due to an internal pull-down
resistor; memory access starts in 16-bit data bus (2-wait)
mode. To start in 8-bit data bus mode, a special operation is
required. Operation is as described in the example below:
B2CS
EQU
ORG
LDX
6AH
8000H
(B2CS), 9CH
; CS2 register address
; RESET address
; CS2 8-bit, 0WAIT, 8000H ~
After reset, the program reads the LDX (B2CS), 9CH
instruction in 16-bit data bus mode. LDX is a 6-byte instruc-
tion: the 2nd, 4th and 6th bytes are handled as dummies (i.e.,
only codes in the 1st, 3rd and 5th bytes are actually used).
Even if starting in 8-bit data bus mode, it is possible to pro-
gram so that the LDX instruction is executed and the block 2
area (8000H - 3FFFFFH) is accessed in 8-bit data bus mode
without any problem.
The above program does not include setting the P42/
CS2 pin to output; add a program to set the P4CR and P4FC
registers as required.
