Interrupts

ST72361xx-Auto

56/279

Doc ID 12468 Rev 3

6.6

External interrupts

6.6.1

I/O port interrupt sensitivity

The external interrupt sensitivity is controlled by the ISxx bits in the EICR register

(Figure 21). This control allows up to four fully independent external interrupt source

sensitivities.

Each external interrupt source can be generated on four (or five) different events on the pin:

●

Falling edge

●

Rising edge

●

Falling and rising edge

●

Falling edge and low level

To guarantee correct functionality, the sensitivity bits in the EICR register can be modified

only when the I1 and I0 bits of the CC register are both set to 1 (level 3). This means that

interrupts must be disabled before changing sensitivity.

The pending interrupts are cleared by writing a different value in the ISx[1:0] of the EICR.
