Freescale Semiconductor

Connector P6 is the ADS SD/MMC connector. Figure 3-16 gives the pin assignments and Table 3-16 gives 
the signal descriptions for this connector.

 

Connectors PE1, PE2 and PE3 are 16 x 3-pin DIN type connectors. PE1 is a connector for the Image 
Sensor module included with the ADS. PE2 and PE3 are Extension connectors that provide most of the 
MC9328MX21 signals other than data bus, address bus, EIM control signals, and SDRAM control signals.

Figure 3-17 shows the pin numbering for the PE1, PE2, and PE3 connectors. Table 3-17 through 
Table 3-19 provide signal descriptions. Table 3-17 covers PE1, Table 3-18 covers PE2 and Table 3-19 
covers PE3.
