Notes to Figure 2:
(1) For more information about the VCC value, refer to the configuration chapter in the appropriate device handbook.
(2) EPCS devices cannot be cascaded.
(3) Connect the MSEL[]input pins to select the AS configuration mode. For more information, refer to the configuration chapter in the appropriate
device handbook.
