values shown in
Listing 2-1. ADSP-21161N EZ-KIT Lite – SDRAM Settings
/* SDRAM Controller Setup for the ADSP-21161N EZ-KIT Lite
/* Assumes SDRAM part# Micron MT48LC16M16A1-7SE (1Mx16-bit,
2 banks)
/* Default Factory Hardware settings (rev2.3)
/* LK_CFG[1:0]= 10,~CLDBL=1
/* CLKIN=25 MHz, => CCLK=100 MHz
/* 3 SDRAMs by 16 bits wide total = 3x(1Mx16-bit) = 1M x 48-bit */
