Introduction
12.2.1 Overview
The TLE9871QXA20 supports 16 interrupt vectors with 16 priority levels. Fifteen of these interrupt vectors are
assigned to the on-chip peripherals: GPT12, SSC, CCU6, DMA, Bridge Driver and A/D Converter are each
assigned to one dedicated interrupt vector; while UART1 and Timer2 or UART2, External Interrupt 2 and Timer21
share interrupt vectors. Two vectors are dedicated for External Interrupt 0 and 1.
