Notes 1:
When BYTE = Vcc level, the external data bus width is fixed to 8 bits.
2:
Burst ROM access is valid only when the external data bus width is 16 bits at instruction prefetch.
3:
Burst ROM access and area multiplexed bus access cannot be used at the same time.
4:
Valid only when area CS
2
is accessed with the 8-bit external data bus width.
5:
Selected by the address output select bit (bit 4 at address 63
