Serial Peripheral Interface (SPI)

The serial peripheral interface (SPI) allows the device to exchange data between other
PowerQUICC family chips, Ethernet PHYs for configuration, and peripheral devices such as EEPROMs,
real-time clocks, A/D converters, and ISDN devices.
The SPI is a full-duplex, synchronous, character-oriented channel that supports a four-wire interface
(receive, transmit, clock, and slave select). The SPI block consists of transmitter and receiver sections, an
independent baud-rate generator, and a control unit.

System Timers

The system includes the following timers:
• Periodic interrupt timer
• Real time clock
• Software watchdog timer
• Two general-purpose timer blocks, each supporting four 16-bit programmable timers, two
cascaded 32-bit timers, or one cascaded 64-bit counter
