AEAW as Fast Boot PLL Multiplier Select (PLLMS)

If FASTBOOT = 1 and AEM[2:0] = 000b [No EMIFA], 011b [8-bit EMIFA (Async) Pinout Mode 3], 100b

[8-bit EMIFA (NAND) Pinout Mode 4], or 101b [8-bit EMIFA (NAND) Pinout Mode 5], the

AEAW[2:0]/PLLMS[2:0] pins serve as PLLMS to select PLL multiplier for Fastboot modes.

For more information on boot modes and the FASTBOOT PLL multiplier selection, see Section 3.4.1, Boot

Modes.

3.5.1.3 PCI Enable (PCIEN)

The PCIEN configuration pin determines if the PCI peripheral is used on this device. If PCIEN = 1

indicating the PCI is used, then the PCI multiplexed pins default to PCI functions, and the pins’

corresponding internal pullup/pulldown resistors are disabled. If PCIEN = 0 indicating the PCI is not used,

then the PCI muxed pins default to non-PCI functions, and the pins’ corresponding internal

pullup/pulldown resistors are enabled.

The PCIEN setting is captured and stored in the BOOTCFG.DPCIEN bit field, and also in the

PINMUX1.PCIEN bit field. These values cannot be changed by software. Furthermore, for proper device

operation, the user must hold the desired setting at the PCIEN pin throughout device operation.
