Are you there is not something else going on? According to the TRM
14.3.1.3.1 + .14.3.1.3.2 the interrupts are properly disabled. So
according to the TRM, the interrupts should not be disabled and not
appear anymore.
Advisory 1.0.9 says that only TXPEND[0] and RXPEND[0] are connected to
the INTC rather than TXPEND[0-7] (+RXPEND) and therefore only channel 0
can be used. That means I have still no idea why the interrupt is not
cleared on your ES2.0.
