CS[7:4] pin assignment. The PAR_CS[7:4] bits configure the CS[7:4] pins for their primary
functions or GPIO.
0 CS[7:4] pins configured for GPIO
1 CS[7:4] pins configured for EIM CS[7:4] function
CS[3:2] Pin Assignment Bit. The PAR_CS[3:2] bits configure the CS[3:2] pins for their
primary functions or GPIO.
0 CS[3:2] pins configured for GPIO
1 CS[3:2] pins configured for EIM CS[3:2] or SD_CS[1:0] function
Note: The selection between the EIM chip select function and SDRAMC chip select
function on each of the CS[3:2] pins is determined by the value of the PAR_SDRAM[7:6]
bits. See
for more details on the PAR_SDRAM bits.
CS1 Pin Assignment Bit. The PAR_CS1 bit configures the CS1 pin for its primary function
or GPIO.
0 CS1 pin configured for GPIO
1 CS1 pin configured for EIM CS1 function
Reserved, should be cleared.
