4.2.5.2 PORT B. Port B pins can be independently programmed to function as chip
selects, IRQ
shown in Figure 4-7. Selection of a pin function is accomplished by a combination of the
port B pin assignment register (PPARB) and the FIRQ bit of the MCR. See Table 4-5 for
port B combinations. By changing the value of the FIRQ bit and the corresponding bits in
the PPARB for a particular signal, the port B pins can be configured for different pin
functions. Upon reset, port B is configured as MODCK, IRQ7, IRQ6, IRQ5, IRQ3 , and
CS3–CS0 .
