Italics indicate mandatory setting for a given Minor Configuration option.
The Sub-Block 1 Minor Configuration Options are independent from the Sub-Block 0 Minor Configuration
Options. The user can independently select the appropriate Minor Configuration Option for each
Sub-Block.
As shown in
Table 3-50
through
Table 3-54
, the configuration choices of the EMIFA/VPSS Sub-Block 1
are determined by the following PINMUX register fields:
PINMUX0 register fields AEM, VENCSEL, RGBSEL, CS3SEL, CS4SEL, CS5SEL, and VPBECKEN.
The following is an example on how to read
Table 3-50
through
Table 3-54
using Sub-Block 1 Minor
Configuration G2 as an example:
The
PINMUX Selection Fields
columns indicate that Sub-Block 1 Minor Configuration Option G2 is
selected through setting PINMUX0 fields to AEM = 5, VENCSEL = 1, RGBSEL = 0 or 1 (based on
whether the VPBE LCD_FIELD pin is needed), CS3SEL = 0/1/2 (based on the desired pin choice),
CS4SEL = 0/1/2 (based on the desired pin choice), CS5SEL = 0/1/2 (based on the desired pin choice),
and VPBECKEN = 0/1 (based on whether VPBE VPBECLK is needed).
The
Resulting Peripherals/Pins
columns show the functional pins resulting from the PINMUX setting.
For example, PINMUX0.VENCSEL = 1 gives you the VCLK and YOUT[7:0] pins for the VPBE, in
addition to EM_D[7:0] pins for the EMIFA. PINMUX0.RGBSEL = 1 gives you the LCD_FIELD pin for
the VPBE, along with EM_A[2:1] and EM_CS2 for the EMIFA, and 4 GP pins.
