The WCH External Trigger and Interrupt controller (EXTI) supports between 8 and 22 lines where each line can trigger an interrupt on rising edge, falling edge, or both edges. Lines are assigned to a group, and each group has a separate interrupt. On the CH32V003/6, there is one group of 8 lines, while on the CH32V208 there are multiple groups with between one and six lines per group. In the same way as the STM32 and GD32, define an EXTI driver that configures the peripheral and an internal interface that can configure individual lines.
