3.13Extension and Image Sensor Connectors

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