Return Format
The query reads the event register and returns a decimal value which corresponds to the binary-weighted
sum of all bits set in the register (see table above). For example, if bit 2 (decimal value = 4) and bit 4
(decimal value = 16) are set (and the corresponding bits are enabled), this query will return +20.
Examples
The following example reads the event register (bits 3 and 4 are set).
