PXD20RM Datasheet, PDF (43/1628 Pages) Freescale Semiconductor, Inc – PXD20 Microcontroller

• Chapter 27, LIN Controller (LINFlexD), describes the LINFlex (Local Interconnect Network
Flexible) controller, which provides UART capabilities as well as an interface to a LIN network.
• Chapter 28, Memory Protection Unit (MPU), describes the block that provides hardware access
control for all memory references generated in the PXD20.
• Chapter 29, Mode Entry Module (MC_ME), describes the module that controls the PXD20 mode
and mode transition sequences in all functional states.
• Chapter 30, Nexus Development Interface (NDI), describes the Nexus Development Interface
(NDI) block, which provides real-time development support capabilities for the PXD20 in
compliance with the IEEE-ISTO 5001-2003 standard.
• Chapter 31, OpenVG Graphics Accelerator (GFX2D), describes a graphics accelerator module.
• Chapter 32, Periodic Interrupt Timer (PIT), describes an array of timers that can be used to initiate
interrupts and trigger DMA channels.
• Chapter 33, Peripheral Bridge (PBRIDGE), describes the interface between the system bus and
lower bandwidth peripherals via the AIPS bridge.
• Chapter 34, Power Control Unit (MC_PCU), describes the controls for the bridge that maps the
PMC peripheral to the MC_PCU address space.
• Chapter 35, Quad Serial Peripheral Interface (QuadSPI), describes a module that provides a
synchronous serial bus for communication with an external peripheral device.
• Chapter 36, Real-Time Clock (RTC/API), describes a free running counter used for time keeping
applications that may be configured to generate an interrupt at a predefined interval.
• Chapter 37, Reset Generation Module (MC_RGM), describes the module that centralizes the
different reset sources and manages the reset sequence of the device.
• Chapter 38, Run-Length Encoding Decoder (RLE_DEC), describes the module that is used to
decode data that has been compressed using a Run Length Encoding (RLE) scheme.
• Chapter 39, Sound Generator Module (SGM), describes the module is a 4-channel sound generator
supporting autonomous audio note generation, mono linear PCM data playback, mixing, and
amplitude control.
• Chapter 40, Static RAM (SRAM), describes the on-chip static RAM (SRAM) implementation, and
covers general operations, configuration, and initialization.
• Chapter 41, Stepper Motor Controller (SMC), describes the SMC, a PWM motor controller
suitable for driving small stepper and air core motors used in instrumentation applications.
• Chapter 42, Stepper Stall Detect (SSD), describes a block that connects to a stepper motor (SM)
with two coils and monitors the movement of the SM.
• Chapter 43, System Integration Unit Lite (SIUL), describes the SIU module, which controls MCU
reset configuration, pad configuration, external interrupt, general-purpose I/O (GPIO), internal
peripheral multiplexing, and the system reset operation.
• Chapter 44, System Status and Configuration Module (SSCM), describes the module that provides
information about the current state and configuration of the system, which may be useful for
configuring application software and for debugging the system.
• Chapter 45, System Timer Module (STM), describes the timer control module.
