Bus Access

5.5.1

Number of clocks for access

The following table shows the number of basic clocks required for accessing each resource.

Area (Bus Width)

Bus Cycle Type

Internal ROM (32 bits)

Internal RAM (32 bits)

External Memory (16 bits)

Instruction fetch (normal access)

1 or 2

3 + n

Note

Instruction fetch (branch)

1 or 2

3 + n

Note

Operand data access

3 + n

Note

2 + n clocks (n: Number of wait states) when the separate bus mode is selected.

Remark

Unit: Clocks/access

5.5.2

Bus size setting function

The bus size of each external memory area selected by CSn can be set (to 8 bits or 16 bits) by using the BSC

The external memory area of the V850ES/SA2 (0100000H to 0BFFFFFH) is selected by CS0 to CS3.

The external memory area of the V850ES/SA3 (0100000H to 0FFFFFFH) is selected by CS0 to CS3.

(1) Bus size configuration register (BSC)

This register can be read or written in 16-bit units.

Caution

Write to the BSC register after reset, and then do not change the set values. Also, do not

access an external memory area other than the one for this initialization routine until the

initial settings of the BSC register are complete. However, external memory areas whose

initial settings are complete may be accessed.

After reset:

5555H R/W

Address:

FFFFF066H

Caution

Be sure to set bits 14, 12, 10, and 8 to 1, and clear bits 15, 13, 11, 9, 7, 5, 3, and 1 to 0.
