Italics indicate mandatory settings for a given Minor Configuration option.

As shown in Table 3-39 through Table 3-41, the configuration choices of the EMIFA/VPSS Sub-Block 0

are determined by the following PINMUX register fields:

• PINMUX0 register fields AEM, AEAW, CCDCSEL, HVDSEL, CWENSEL, CFLDSEL, and CI10SEL.

The following is an example of how to read Table 3-39 through Table 3-41 using Sub-Block 0 Minor

Configuration B6 as an example:

• The PINMUX Selection Fields columns indicate that Sub-Block 0 Minor Configuration Option B6 is

selected through setting, PINMUX0.AEM = 1, PINMUX0.AEAW = 4, CCDCSEL = 1, HVDSEL = 0 or 1

(based on the system’s need for VPFE control signals VD and HD), CWENSEL = 0 (mandatory

setting), CFLDSEL = 0 or 1 (based on the system’s need for VPFE control signal C_FIELD), and

CI10SEL = 0 (mandatory).

• The Resulting Peripherals/Pins columns show the functional pins resulting from the PINMUX setting.

For example, PINMUX0.CCDCSEL = 1 gives the user the PCLK and YI[7:0] pins for the VPFE.

PINMUX0.HVDSEL = 1 gives the user VD and HD pins for VPFE, while HVDSEL = 0 gives the user 2

GP pins.
