Datasheet

4.5.6.5 Carrier Modulator Timer (CMT)
• Four modes of operation
• Time with independent control of high and low times
• Baseband
• Frequency shift key (FSK)
• Direct software control of CMT_IRO signal
• Extended space operation in time, baseband, and FSK modes
• Selectable input clock divider
• Interrupt on end of cycle
• Ability to disable CMT_IRO signal and use as timer interrupt
4.5.6.6 Real-Time Clock (RTC)
• Independent power supply, POR and 32 kHz crystal oscillator
• 32-bit seconds counter with 32-bit alarm
• 16-bit prescaler with compensation
• Register write protection
• Hard Lock requires VBAT POR to enable write access
• Soft lock requires system reset to enable write/read access
Communication interfaces
4.5.7.1 CAN Module
• Supports the full implementation of the CAN Specification Version 2.0, Part B
•
Standard data and remote frames (up to 109 bits long)
• Extended data and remote frames (up to 127 bits long)
• 0–8 bytes data length
• Programmable bit rate up to 1 Mbit/sec
• Content-related addressing
• Flexible message buffers (MBs), totalling up to 16 message buffers of 0–8 bytes data length each, configurable as Rx
or Tx, all supporting standard and extended messages
• Listen-only mode capability
• Individual mask registers for each message buffer
• Programmable transmit-first scheme: lowest ID or lowest buffer number
• Timestamp based on 16-bit free-running timer
• Global network time, synchronized by a specific message
4.5.7.2 Serial Peripheral Interface (SPI)
• Master and slave mode
• Full-duplex, three-wire synchronous transfers
• Programmable transmit bit rate
• Double-buffered transmit and receive data registers
• Serial clock phase and polarity options
