abb_inth.c: check all interrupt causes, not just one The original code used if - else if - else if etc constructs, thus the first detected interrupt was the only one handled. However, Iota ITSTATREG is a clear-on-read register, thus if we only handle the first detected interrupt and skip checking the others, then the other interrupts will be lost, if more than one interrupt happened to occur in one ABB interrupt handling cycle - a form of rare race condition. Change the code to check all interrupts that were read in this cycle.

15 Description: The sample sends a STOP DTMF message without release of the key by the user

16 Solution: Instead of sending DTMF commands in "VTS_MOD_Auto" mode, on key press DTMF tone is started

17 using VTS_MOD_ManStart and on key release DTMF tone is stopped using VTS_MOD_ManStop mode.
