presence and number of blocks vary by device and package.
Table 2. MPC5604B/C series block summary
Block
Function
Analog-to-digital converter (ADC) Multi-channel, 10-bit analog-to-digital converter
Boot assist module (BAM)
A block of read-only memory containing VLE code which is executed according
to the boot mode of the device
Clock monitor unit (CMU)
Monitors clock source (internal and external) integrity
Cross triggering unit (CTU)
Enables synchronization of ADC conversions with a timer event from the eMIOS
or from the PIT
Deserial serial peripheral interface
(DSPI)
Provides a synchronous serial interface for communication with external devices
Error Correction Status Module
(ECSM)
Provides a myriad of miscellaneous control functions for the device including
program-visible information about configuration and revision levels, a reset status
register, wakeup control for exiting sleep modes, and optional features such as
information on memory errors reported by error-correcting codes
Enhanced Direct Memory Access
(eDMA)
Performs complex data transfers with minimal intervention from a host processor
via “
n” programmable channels.
Enhanced modular input output
system (eMIOS)
Provides the functionality to generate or measure events
Flash memory
Provides non-volatile storage for program code, constants and variables
FlexCAN (controller area network) Supports the standard CAN communications protocol
Frequency-modulated
phase-locked loop (FMPLL)
Generates high-speed system clocks and supports programmable frequency
modulation
Internal multiplexer (IMUX) SIU
subblock
Allows flexible mapping of peripheral interface on the different pins of the device
Inter-integrated circuit (I2C) bus A two wire bidirectional serial bus that provides a simple and efficient method of
data exchange between devices
Interrupt controller (INTC)
Provides priority-based preemptive scheduling of interrupt requests
JTAG controller
Provides the means to test chip functionality and connectivity while remaining
transparent to system logic when not in test mode
LINFlex controller
Manages a high number of LIN (Local Interconnect Network protocol) messages
efficiently with a minimum of CPU load
Clock generation module
(MC_CGM)
Provides logic and control required for the generation of system and peripheral
clocks
Mode entry module (MC_ME)
Provides a mechanism for controlling the device operational mode and mode
transition sequences in all functional states; also manages the power control unit,
reset generation module and clock generation module, and holds the
configuration, control and status registers accessible for applications
Power control unit (MC_PCU)
Reduces the overall power consumption by disconnecting parts of the device
from the power supply via a power switching device; device components are
grouped into sections called “power domains” which are controlled by the PCU
Reset generation module
(MC_RGM)
Centralizes reset sources and manages the device reset sequence of the device
