Bus Settings
Table 1.8.1. Factors for switching bus settings
The BYTE pin and bits 4 to 6 of the processor mode register 0 (address 0004
Table 1.8.1 shows the factors used to change the bus settings.
(1) Selecting external address bus width
(2) Selecting external data bus width
(3) Selecting separate/multiplex bus
Switching external address bus width
Switching external data bus width
Switching between separate and multiplex bus
The address bus width for external output in the 1M bytes of address space can be set to 16 bits (64K
bytes address space) or 20 bits (1M bytes address space). When bit 6 of the processor mode register 0
is set to “1”, the external address bus width is set to 16 bits, and P2 and P3 become part of the address
bus. P4
to “0”, the external address bus width is set to 20 bits, and P2, P3, and P4
address bus.
The external data bus width can be set to 8 or 16 bits. (Note, however, that only the separate bus can be
set.) When the BYTE pin is “L”, the bus width is set to 16 bits; when “H”, it is set to 8 bits. (The internal bus
width is permanently set to 16 bits.) While operating, fix the BYTE pin either to “H” or to “L”.
The bus format can be set to multiplex or separate bus using bits 4 and 5 of the processor mode register 0.
• Separate bus
• Multiplex bus
In this mode, the data and address are input and output separately. The data bus can be set using the
BYTE pin to be 8 or 16 bits. When the BYTE pin is “H”, the data bus is set to 8 bits and P0 functions as
the data bus and P1 as a programmable I/O port. When the BYTE pin is “L”, the data bus is set to 16
bits and P0 and P1 are both used for the data bus.
When the separate bus is used for access, a software wait can be selected.
In this mode, data and address I/O are time multiplexed. With the BYTE pin = “H”, the 8 bits from D
D
With the BYTE pin = “L”, the 8 bits from D
multiplexed. In this case, the external devices connected to the multiplexed bus are mapped to the
microcomputer’s even addresses (every 2nd address). To access these external devices, access the
even addresses as bytes.
The ALE signal latches the address. It is output from P5
Before using the multiplex bus for access, be sure to insert a software wait.
If the entire space is of multiplexed bus in memory expansion mode, choose an 8-bit width.
The processor operates using the separate bus after reset is revoked, so the entire space multiplexed
bus cannot be chosen in microprocessor mode.
