One serial peripheral interface (SPI)
— Full-duplex operation
— Master and slave modes
— Programmable length transactions (2 to 16 bits)
— Programmable transmit and receive shift order (MSB as first or last bit transmitted)
— Maximum slave module frequency = module clock frequency/2
One inter-integrated Circuit (I
— Operates up to 400 kbps
— Supports master and slave operation
— Supports 10-bit address mode and broadcasting mode
— Supports SMBus, Version 2
One 16-bit programmable interval timer (PIT)
— 16 bit counter with programmable counter modulo
— Interrupt capability
One 16-bit programmable delay block (PDB)
— 16 bit counter with programmable counter modulo and delay time
— Counter is initiated by positive transition of internal or external trigger pulse
— Supports two independently controlled delay pulses used to synchronize PGA and ADC conversions with input
— Two PDB outputs can be ORed together to schedule two conversions from one input trigger event
— PDB outputs can be can be used to schedule precise edge placement for a pulsed output that generates the control
— Supports continuous or single shot mode
— Bypass mode supported
Computer operating properly (COP)/watchdog timer capable of selecting different clock sources
— Programmable prescaler and timeout period
— Programmable wait, stop, and partial powerdown mode operation
— Causes loss of reference reset 128 cycles after loss of reference clock to the PLL is detected
— Choice of clock sources from four sources in support of EN60730 and IEC61508:
Real-timer counter (RTC)
— 8-bit up-counter
— Three software selectable clock sources
— Can signal the device to exit power down mode
Phase lock loop (PLL) provides a high-speed clock to the core and peripherals
— Provides 3x system clock to PWM and dual timer and SCI
— Loss of lock interrupt
— Loss of reference clock interrupt
