As shown in Table 3-42, the major configuration choices of the EMIFA/VPSS Block are determined by the
following PINMUX register fields:
• PINMUX1 register field PCIEN
• PINMUX0 register fields AEM, VENCSEL, CCDCSEL
Based on the peripheral needs, select from the major configuration options in this block: Major
Configuration Options A, B, C, D, E, F, and G.
The following is an example on how to read Table 3-42. For example, the "PINMUX Selection Fields"
columns indicate that Major Configuration Choice B is selected through setting PINMUX1.PCIEN = 0,
PINMUX0.AEM = 1, VENCSEL = 0 or 1 (based on the system's VPBE requirement), and CCDCSEL = 0
or 1 (based on the system's VPFE requirement). The "Resulting Peripherals/Pins" columns indicate that
Major Configuration Option B can support the following combination of pin functions:
• No PCI pins
• Pins for 8-bit EMIFA (Async or NAND) function. The number of address pins supported provide
32KByte to 16MByte address reach per EMIFA Chip Select (CS) space.
• Pins for up to 8-bit VPBE. If 8-bit VPBE (VENCSEL = 1) is selected, the user may have 0 to 4 GPIO
pins. Exact detail on number of GPIO pins and VPBE control pins is further determined by other
PINMUX0 settings discussed in the EMIFA/VPSS Sub-Block 1 Configuration Choices.
• Pins for up to 16-bit VPFE. If 8 to 16-bit VPFE (CCDCSEL = 1) is selected, the user may have 0 to 10
GPIO pins. Exact detail on number of GPIO pins and VPFE control pins is furthered determined by
other PINMUX0 settings discussed in the EMIFA/VPSS Sub-Block 0 Configuration Choices.
After using Table 3-42 to select the Major Configuration Option for the EMIFA/VPSS Block, proceed to
select the detailed pin choices in the EMIFA/VPSS Sub-Blocks.
