Bits 7 to 4

⎯Reserved: These bits read 0 after a reset. The write value should always be 0.

Operation is not guaranteed if the write value is 1.

Bit 3

⎯CS3 Space Size Specification (A3SZ): Specifies the CS3 space bus size. This is effective

only when CS3 space is ordinary space. When CS3 space is an address/data multiplex I/O space,

bus size is decided by the A14 bit.

Bit 3

A3SZ

Description

Byte (8-bit) size

(initial value)

Bit 2

⎯CS2 Space Size Specification (A2SZ): Specifies the CS2 space bus size.

Bit 2

A2SZ

Description

Byte (8-bit) size

Word (16-bit) size

(initial value)

Bit 1

⎯CS1 Space Size Specification (A1SZ): Specifies the CS1 space bus size.

Bit 1

A1SZ

Description

Byte (8-bit) size

Word (16-bit) size

(initial value)

Bit 0

⎯CS0 Space Size Specification (A0SZ): Specifies the CS0 space bus size.

Bit 0

A0SZ

Description

Byte (8-bit) size

Word (16-bit) size

(initial value)

Note:

A0SZ is effective only in on-chip ROM effective mode. In on-chip ROM ineffective mode,

the CS0 space bus size is specified by the mode pin.
