This block defaults to CLKOUT0 pin function.

In addition, the VDD3P3V_PWDN.CLKOUT field determines the power state of the CLKOUT Block pin.

The CLKOUT Block pin defaults to powered up. For more details on the VDD3P3V_PWDN.CLKOUT field,

see Section 3.2, Power Considerations.

3.7.3.13 EMIFA Block Muxing

This block of 61 pins consists of EMIFA, EMAC(RMII), PCI, and GPIO muxed pins. The following register

fields affect the pin functions in the EMIFA Block:

•

All PINMUX0 register fields: AEM, CS5SEL, CS4SEL, CS3SEL, and RMII.

•

PINMUX1.PCIEN

As discussed in Section 3.7.3.2, Peripherals Spanning Multiple Pin Mux Blocks, PCI pins span across the

following Pin Mux Blocks: Host Block, EMIFA Block Sub-Block 0 and Sub-Block 3, PCI Data Block, and

GPIO Block. For proper PCI operation, PCI must be selected in all of these Pin Mux Blocks.

There is only one EMAC peripheral on the C6424 device, even though the pins for MII mode and the pins

for RMII modes are brought out to different locations. The EMAC MII mode pins are in the Host Block,

while EMAC RMII mode pins are only in the EMIFA Block. The user is only allowed to select either the MII

pins or the RMII pins. The operation is undefined if the user attempts to select both MII pins and RMII

pins.

The EMIFA Block is divided into multiple sub-blocks for ultimate flexibility in pin multiplexing to

accommodate a wide variety of applications, and for the purpose of I/O pins power control:

•

Sub-Block 0: multiplexed between EMIFA data/address/control pins, PCI, part of EMAC(RMII), and

GPIO.

•

Sub-Block 1: multiplexed between EMIFA data/address/control pins, part of EMAC(RMII), and GPIO.

•

Sub-Block 2: no multiplexing. EMIFA control pins EM_WAIT/(RDY/BSY), EM_OE, EM_WE.

•

Sub-Block 3: multiplexed between EMIFA address pins EM_A[12:6], PCI, and GPIO.

The EMBK0, EMBK1, EMBK2, EMBK3 fields in the VDD3P3V_PWDN register determine the power state

of the EMIFA Block pins. The EMIFA Block pins default to powered up. For more details on the EMBK0,

EMBK1, EMBK2, EMBK3 fields in the VDD3P3V_PWDN register, see Section 3.2, Power Considerations.
