14.5.8 Selecting the Flash Bank (SEFC0 or SEFC1)

Some product parts embed two Flash banks, each controlled by the corresponding Flash controllers: either SEFC0 or SEFC1. All Flash operations, such as EA or SLB, access only the selected Flash bank. By default, the bank controlled by SEFC0 is selected. The SFB operation changes the selected Flash bank according to the input value of the DATA command following the CMDE command:

  • 0: Flash Bank 0 (SEFC0) is selected
  • 1: Flash Bank 1 (SEFC1) is selected
