is output in the master mode and is input in the slave mode. If the SPI system is

disabled, i.e. SPEN (SPCTL.6) = 0 (reset value), these pins are conﬁgured for port

functions.

• SS is the optional slave select pin. In a typical conﬁguration, an SPI master asserts

one of its port pins to select one SPI device as the current slave. An SPI slave

device uses its SS pin to determine whether it is selected.

Typical connections are shown in Figure 18, 19, and 20.

• The 89LPC913 does not have the slave select pin, SS. The SPI interface is set to

Master mode and an I/O pin may be used to implement the SS function. Typical

connections are shown in Figure 18 and 19.
