PRU INTC功能及寄存器

请问芯片型号是什么？

OMAP-L138

参考这个文档PRU_Interrupt_Controller：
processors.wiki.ti.com/.../PRU_Interrupt_Controller

1、第一问是什么意思？
2、是通道号
GPIR是所有的host interrupt
HIPIR0是特定的host interrupt
请看TRM 14.7.5.6 Interrupt Prioritization
www.ti.com/.../spruh77c.pdf
3、通道号
channel有默认的优先级：Channel 0 has the highest priority and channel 9 has the lowest.
nesting level相当于channel优先级的嵌套。
GNLR：The nesting level is the channel (and all of lower priority channels) that are nested out because of a current interrupt.
HINLR0：The nesting level controls which channel and lower priority channels are nested. There is one register per host interrupt

可以结合TRM：14.7 PRU Interrupt Controller看。

谢谢您的回复！

关于GPIR，我看到“14.8.2.11 GLBLPRIIDX Register (Offset = 80h)
The Global Prioritized Index Register shows the interrupt number of the highest priority interrupt pending
across all the host interrupts. ”，  感觉好像又是中断号，让我有点疑惑；收到您的回复应该确定是通道号了。谢谢！
