STM8S and EXTI and Continuous Interrupts

Question asked by Workalot on Jan 24, 2012

MCU: STM8S105C6
Port: GPIOB
Bit: 2 

GPIOB:2 is the only pin/bit set up for external interrupt, yet regardless of any edge sensitivity setting in EXTI_CR1, once an interrupt is invoked it is continuously invoked while ever the input pin is low. As the STM8S appears to have has no register for clearing an interrupt flag, what mechanism am I missing?   

Other posts have discussed similar experiences but have not been conclusive in an answer.

The project manipulates registers directly rather than through ST's FWLIB.
