Interrupt conditions occurring while masked are not being
signaled when later unmasked.
The fix is to raise/lower IRQs when IMASK is changed.
To avoid problems like this in future, consolidate
IRQ pin update logic in one function.
Also fix probable typo "IEVENT_TXF | IEVENT_TXF",
and update IRQ pins on reset.
