Switch S1 2.2.2 Mode/User Switch (S2) S2 is a DIP switch that consists of eight slide switches. S2-1 to S2-4 configure boot mode and S2-5 and S2-6 control the clock bypass modes. These switch settings take effect only on power up or after a reset. S2 also provides two user definable switches (S2-7 and S2-8).

Configuration and Operation 2.3.8 CD Quality CODEC The ADS has a Wolfson WM8731SEDS 32-bit linear low power stereo CODEC with a built-in headphone driver (U24). The CODEC is controlled by the i.MX21, which sends the digital audio data via an SSI2 interface and control data via an I2C interface. The CODEC has stereo line and mono microphone level audio inputs as well as stereo headphone outputs.
PAGE 20
Configuration and Operation 2.3.10 Memory Mapped I/O The ADS uses Memory Mapped I/O to add I/O functions without using the I/O resources of the processor. The following paragraphs describe the I/O functions. 2.3.10.1 Input I/O A memory read of hex address 0xCC80_0000 inputs the state of the ADS signals connected to latches U5 and U7. Table 2-7 shows which signal is associated with each data bit. Table 2-7.
PAGE 21
Configuration and Operation 2.3.10.2 Output I/O A memory write to hex address 0xCC80_0000 causes U5 and U7 to latch the logic state of the data bus. Each latch output is associated with the data bus signal of the same number (Bit 0 is equal to DATA0, and so on). All output bits are forced to logic 0 (low) on power up or reset. Table 2-8 shows the functions associated with each data bit. Table 2-8.
PAGE 22
Configuration and Operation 2.3.11 Audio Indicator (Buzzer) The ADS includes an audio indicator or buzzer, U23. When S1-6 is ON, the PWMO pin of the i.MX21 controls this function. This buzzer operates from 1 KHz to 10 KHz. The maximum sound level is reached when the frequency is 3 KHz and the duty cycle is 50%. 2.3.12 LED Indicators Table 2-9 shows the ADS LED indicators and their associated functions. Table 2-9.

Configuration and Operation 2.5.2 Using the Keypad To use the keypad module, connect the 20 conductor ribbon cable supplied with the ADS from connector P1 of the Keypad module to P5 of the M9328MX21ADSE Base board. 2.5.3 Using a NAND Flash Card CAUTION To avoid circuit damage, do not plug-in the NAND Flash card with power applied to the board. To use the NAND Flash module supplied with the ADS, connect PN1 & PN2 of the NAND Flash module to PM1 & PM2 on the CPU board.
PAGE 27
Configuration and Operation 2.5.7 Using the TV Encoder Card A TV encoder card is supplied with the ADS. The main component is a FS453LF (PC to TV Video Scan converter) from FOCUS Enhancements Semiconductor. For details on TV encoder operation, refer to its data sheet, available at http://www.focusinfo.com/ CAUTION Make sure that input power is disconnected or switched off before the TV encoder card is installed. Connecting the card with power applied can damage the TV encoder card and the Base board.
