Operand data access
The following table shows the number of basic clocks required for accessing each resource.
Notes 1. Increases by 1 if a conflict with a data access occurs.
Remark
Each external memory area selected by memory block n can be set by using the BSC register. However, the bus
The external memory area of the V850ES/JG3-L is selected by memory blocks 0 to 3.
(1) Bus size configuration register (BSC)
Bus Access
The BSC register can be read or written in 16-bit units.
Reset sets this register to 5555H.
Caution Write to the BSC register after reset, and then do not change the set values. Also, do not
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”.
Number of clocks for access
Bus size setting function
2. 2 + n clocks (n: Number of wait states) when the separate bus mode is selected.
