Cache Program Operation Flow Diagram
NOTE :
1) DBS must be set before data input.
2) FSA must be 00 and BSC must be 000 within program operation.
3) BSA must be 1000.
4) Writing System Configuration Register is optional.
5) ‘Write 0 to interrupt register’ step may be ignored when using INT auto mode. Refer to chapter 2.8.18.1
