Notes 1.
If both the CS0m and CS2m bits have been set to 0, if area 0 is accessed, CS1 will be output
regardless of the setting of the CS1m bit.
2.
When area 1 is accessed, CS3 will be output regardless of the setting of the CS3m bit.
3.
When area 2 is accessed, CS4 will be output regardless of the setting of the CS4m bit.
4.
If both the CS5m and CS7m bits have been set to 0, if area 3 is accessed, CS6 will be output
regardless of the setting of the CS6m bit.
Caution In the V850E/IA2, set the CS01 and CS00 bits to 11B so that CS0 is output to both block 0 and 1.
