Cyclone IV E devices support the active parallel (AP) configuration scheme for Altera devices.
When used with EPCS or EPCQ devices, the remote update mode allows a configuration space to start at
any flash sector boundary, allowing a maximum of 128 pages in the EPCS64 device and 32 pages in the
EPCS16 device, in which the minimum size of each page is 512Kbits. Additionally, the remote update
mode features a user watchdog timer that can detect functional errors in an application configuration.
