11.4.1.6.7 Event Enable Set Registers (EESR, EESRH)
The event enable registers (EER/EERH) cannot be modified by directly writing to them. The intent is to
ease the software burden for the case where multiple tasks are attempting to simultaneously modify these
registers. The event enable set registers (EESR/EESRH) are used to enable events. Writes of 1 to the bits
in EESR/EESRH set the corresponding event bits in EER/EERH; writes of 0 have no effect.
The EESR is shown in
and described in
. The EESRH is shown in
and described in
