Solution

The bits that control the external interrupts are EX0 and EX1.

Here's a step-by-step explanation:

  1. EX0: This is the enable bit for Interrupt 0. When this bit is set to 1, the external interrupt 0 is enabled. When it's set to 0, the interrupt is disabled.

  2. EX1: This is the enable bit for Interrupt 1. Similar to EX0, when this bit is set to 1, the external interrupt 1 is enabled. When it's set to 0, the interrupt is disabled.

So, the bits that control the external interrupts are EX0 and EX1. ET0 and ET1 are used for timer interrupts, not external interrupts.
