• Activation sources: Activated by interrupt sources (30 to 33 sources).
• Chain transfer function
Note 1.
Although the CSI function is generally called SPI, it is
also called CSI in this product, so it is referred to as
such in this manual.
Event link controller (ELC)
Note 2.
Note 3.
Remark
The number in parentheses indicates the number of
signal outputs when 8 coms are used.
• Event signals of 30 or 31 types can be linked to the specified
peripheral function.
Selectable only in HS (high-speed main) mode.
Serial interfaces
Note 1
• Simplified SPI (CSI
): 4 channels
The functions mounted depend on the product. See
• UART/UART (LIN-bus supported): 4 channels
