Just realized that a few lines below ERQ0 some bit fields are defined
(AP[0-7]) that are actually on the same address as the ERQ0 byte. This
makes
a lot of sense as AP[0-7] are written by WSIO (aka what wmi_set_block
calls here).

Just tried setting a random bit of AP* and events started flowing in. Thank you!
