3.13 Extension 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 3-17 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.
