Freescale Semiconductor
8
— Advanced error detection, and optional parity generation and detection
— Word length programmable as 8, 9, 12 or 13 bits
— Separately enabled transmitter and receiver
— LIN support
— DMA support
— Interrupt request support
— Programmable clock source: system clock or oscillator clock
— Support Microsecond Channel (Timed Serial Bus - TSB) upstream Version 1.0
Two FlexCAN
— One with 32 message buffers; the second with 64 message buffers
— Full implementation of the CAN protocol specification, Version 2.0B
— Based on and including all existing features of the Freescale TouCAN module
— Programmable acceptance filters

— Programmable clock source: system clock or oscillator clock
— Message buffers may be configured as mailboxes or as FIFO
Nexus port controller (NPC)
— Per IEEE-ISTO 5001-2003
— Real time development support for Power Architecture core and eTPU engine through Nexus class 2/1
— Read and write access (Nexus class 3 feature that is supported on this device)
– Run-time access of entire memory map
– Calibration
— Support for data value breakpoints / watchpoints
– Run-time access of entire memory map
– Calibration
Table constants calibrated using MMU and internal and external RAM
Scalar constants calibrated using cache line locking
— Configured via the IEEE 1149.1 (JTAG) port
IEEE 1149.1 JTAG controller (JTAGC)
— IEEE 1149.1-2001 Test Access Port (TAP) interface
— 5-bit instruction register that supports IEEE 1149.1-2001 defined instructions
— 5-bit instruction register that supports additional public instructions
— Three test data registers: a bypass register, a boundary scan register, and a device identification register
— Censorship disable register. By writing the 64-bit serial boot password to this register, Censorship may be disabled
until the next reset
— TAP controller state machine that controls the operation of the data registers, instruction register and associated
circuitry
On-chip Voltage Regulator for single 5 V supply operation
— On-chip regulator 5 V to 3.3 V for internal supplies
— On-chip regulator controller 5 V to 1.2 V (with external bypass transistor) for core logic
Low-power modes
— SLOW Mode. Allows device to be run at very low speed (approximately 1 MHz), with modules (including the PLL) selectively
disabled in software
— STOP Mode. System clock stopped to all modules including the CPU. Wake-up timer used to restart the system
clock after a predetermined time
