Errored Second Mask
This register functions as an additional mask register for the interrupt
status bit Errored Second (ISR3.ES). A ‘1’ in a bit position of ESM sets
the mask active for the interrupt status.

in the error counter CEC3L.1-0.
Multiframe periods received in the asynchronous state are
accumulated in the error counter CEC3L.7-2.
An overflow of each counter is disabled.
All outputs are driven inactive, except the multifunction ports,
which are driven high.
