Logical OR of all other interrupt
flags
GPIO4 interrupt
0 = interrupt not set
1 = interrupt is set
Cleared when a ‘1’ is written
Write Sequence interrupt
0 = interrupt not set
1 = interrupt is set
Cleared when a ‘1’ is written.
Note that the read value of
WSEQ_EINT is not valid whilst
the Write Sequencer is Busy
