C)
• A/D converter : 32 channels (1 unit)
• Series-parallel type
• Resolution: 10 bits
• Minimum conversion time: 3us
• Single conversion mode
• Continuous conversion mode
• Stop conversion mode
• Activation by software or external trigger can be selected
• Reload timer 7 and A/D Converter co-operate
• D/A converter : 2 channels
• R-2R type
• Resolution: 10 bits
• Conversion rate: 0.45us (when 20 pF load is applied)
• Conversion rate: 2us (when 100 pF load is applied)
• Alarm comparator : 2 channels
• Monitors an external voltage and generates an interrupt in case of a voltage lower or higher than the
defined thresholds
• Status is readable, interrupts can be masked separately
• External interrupt input : 16 channels
• Can be programmed to be edge sensitive or level sensitive
• Interrupt mask and request pending bits per channel
• 6 channels combined with CAN RX for wakeup
• Non maskable interrupt (NMI) : 1 channel
• Highest priority of all user interrupts
• Bit search module (using REALOS)
• Function to search the first bit position of “1”, “0”, “Changed” from MSB (most significant bit) within 1
word
• Up/down counter : 16 bits x 2 channels (8 bits x 4 channels)
• Timer mode, up/down count mode, phase difference mode (x2, x4)
• Includes clock prescaler (f
