PXS20RM Datasheet, PDF (36/1368 Pages) Freescale Semiconductor, Inc – PXS20 Microcontroller

• Chapter 8, Boot Assist Module (BAM), describes the BAM, which contains the MCU boot
program code supporting the different booting modes for this device.
• Chapter 9, Analog-to-Digital Converter (ADC), describes the ADC module implemented on the
PXS20.
• Chapter 10, Clock Architecture, describes the various clock sources that are available on the
PXS20.
• Chapter 11, Clock Generation Module (MC_CGM), describes the clock generation module
(MC_CGM), which generates reference clocks for all the on-chip modules.
• Chapter 12, Clock Monitor Unit (CMU), describes the module that monitors the external crystal
oscillator clock, detects whether the PLL leaves an upper or lower frequency boundary, and
measures the frequency of the IRCOSC versus a known reference clock XOSC.
• Chapter 13, Cross-Triggering Unit (CTU), describes the CTU block, which converts the events
generated by the ADC, the PWM, and various timers into ADC conversion requests.
• Chapter 14, Cyclic Redundancy Checker (CRC) Unit, describes the computing unit that is
dedicated to the computation of CRC, thus off-loading the CPU.
• Chapter 15, Crossbar Switch (XBAR), describes the multi-port AXBS crossbar switch that
supports simultaneous connections between the master and slave ports.
• Chapter 16, Deserial Serial Peripheral Interface (DSPI), describes the serial peripheral interface
(SPI) block, which provides a synchronous serial interface for communication between the PXS20
and external devices.
• Chapter 17, e200z4d Core Complex Overview, describes the organization of the e200z4d Power
processor core and gives an overview of the programming models as they are implemented on the
device.
• Chapter 18, eDMA Channel Mux (DMA_MUX), describes the DMA multiplexer block
implemented on the PXS20.
• Chapter 19, Enhanced Direct Memory Access (eDMA), describes the enhanced DMA controller
implemented on the PXS20.
• Chapter 20, Enhanced Motor Control Timer (eTimer), describes a set of modules containing six
identical counter/timer channels.
• Chapter 21, Error Correction Status Module (ECSM), describes the ECSM block, which provides
monitoring and control functions to report memory errors and apply error-correcting code (ECC)
implementations.
• Chapter 22, Fault Collection and Control Unit (FCCU), describes a programmable redundant
hardware channel that collects errors and leads the device in a controlled way to a safe state when
a failure is present in the device.
• Chapter 23, Flash Memory, describes the flash memory block and the flash memory controller.
• Chapter 24, FlexCAN Module, describes the FlexCAN module, a communication controller
implementing the CAN protocol according to Bosch Specification version 2.0B and ISO Standard
11898.
• Chapter 25, Flexible Motor Control Pulse Width Modulator Module (FlexPWM), describes the
pulse width modulator (PWM) module.
