The bit position in the
register.
The name of the register
bit. A '–' means Not Used
and therefore a write to
such a bit position will get
lost.
The digit is the reset value.
Indicates if the bit position
is a read-only (R), readable
and writable (RW) or
write-only (W).
REGISTER DESCRIPTIONS
This section describes the functionality of each register and its corresponding bits.
Interrupt Register (address 0x00)
The Interrupt Register contains the 12 interrupt flags together with the acknowledge flags. If an interrupt occurs
(that is, when the output of the comparator filter is above the high level threshold or below the low level
threshold, or when one of the modulators is not functional), the appropriate interrupt flag is set (if enabled). An
interrupt flag is reset when the Interrupt Register is read and the corresponding interrupt source is no longer
active. The acknowledge bits are reset when the corresponding data register is read. Table 13 describes the
Interrupt Register.
