4.11.6.2
The twisted-pair port connector P4 is a 8 pin, RJ-45 connector as shown in FIGURE 2-6.
The list below describes the port signals. The directions ’I’, ’O’, and ’I/O’ are relative to the M68360QUADS-
040 board. (I.E. ’I’ means input to the M68360QUADS-040)
4.11.7
The MCM2814 Serial EEPROM (U14) is a 256 bytes EEPROM with SPI interface. It is controlled by the
SPI port of the slave QUICC (pins 1,2 and 3 of port B), and by a general purpose output pin (pin 0 of port
B). The SPI port operates in master mode.
The serial EEPROM serves as non-volatile memory on the M68360QUADS-040 and may be used to store
software parameters to be protected from power-downs.
4.11.8
The slave QUICC has three ports, A, B, and C, whose pins can be individually configured by software to
be general purpose I/O pin or dedicated peripheral function. The QUICC also has another port, E, whose
pins are not general purpose I/O, but they can be configured to operate in one of two possible modes.
The following subsections describe the slave QUICC ports. Refer to 3.4 on page 21 for the required
programming information.
