Table 156. ITC_TLISensitivity
Note: This function is for ST72F521, ST72F561 and ST72325 devices.
EXAMPLE:
The following C program shows the use of the ITC library functions.
Program description:
This program is written for the ST72F521 device. It sets the Software priority level for EI0 Ex-
ternal interrupt & TIMERA peripheral interrupt to Level2. Then it sets the software priority of
EI2 to Level1. The sensitivity of PA0 (EI0 interrupt pin in ST72F521) and PF0 (EI2) interrupt is
set to falling edge. The TLI interrupt is enabled and the sensitivity of the TLI pin is set to Falling
edge. A falling edge is applied on the PF0 pin (configured as input interrupt) to generate an
EI2 interrupt. Immediately after this, a falling edge is applied on the PA0 pin. As the priority of
the EI0 interrupt is higher than EI2, the EI2 interrupt is interrupted and control goes to EI0.
Then TLI interrupt is generated by applying a falling edge on the TLI pin. The LEDs connected
to the Port D pins are toggled by the interrupt subroutines.
