有关 LP55231 / LP5523 的问题

在 LP55231 datasheet 中 engines 和 bank 的概念。 请问这两个应该怎样理解。

The LP55231 has three independent program execution engines, so it is possible to form three independently
programmable LED banks. LED drivers can be grouped based on their function so that, for example, the first
bank of drivers can be assigned to the keypad illumination, the second bank to the funlights, and the third group
to the indicator LED(s).

answer：

三个BANK，可以理解为三个功能块，分别实现不同的功能，比如一个块可能用于键盘灯，另一个块可能用于指示。
