i would like to configure the P1.11 as external interrupt. how do you it? It is possible to show me what register are configured to use correctly this pin. thanks Ludovic
Some ports (like P1.11) have external interrupt capability . To use external interrupts, the port must be configured in input mode. Each of the General Purpose I/O Ports has three 16-bit configuration registers (PC0, PC1,PC2) and one 16-bit Data register (PD). You can refer to the STR71x Ref Man for more details. Regards, Hich
