Operand data access
The following table shows the number of basic clocks required for accessing each resource.
Note Increases by 1 if a conflict with a data access occurs.
Remark
Each external memory area selected by memory block CSn can be set by using the BSC register. However, the

(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
Note V850ES/JJ3-E only. Be sure to set this bit to 1 in the V850ES/JH3-E.
Caution Be sure to set bits 14, 12, 10, 8, and 2 to “1”, and clear bits 15, 13, 11, 9, 7, 5, 3, and 1 to “0”.
