Production Data
The secondary interrupt can be masked. When the mask bit is set, the corresponding interrupt event
is masked and does not trigger a TEMP_INT interrupt. The secondary interrupt bit in R16401 (4011h)
is valid regardless of whether the mask bit is set. The secondary interrupt is masked by default.

23.2.3 GPIO INTERRUPTS
The primary GP_INT interrupt comprises sixteen secondary interrupts as described in Section 21.4.
The secondary interrupt bits are defined in Table 67.
Each of the secondary interrupts can be masked. When a mask bit is set, the corresponding interrupt
event is masked and does not trigger a GP_INT interrupt. The secondary interrupt bits in R16405
(4015h) are valid regardless of whether the mask bit is set. The secondary interrupts are all masked
by default.

23.2.4 ON PIN INTERRUPTS
The primary ON_PIN_INT interrupt comprises a single secondary interrupt as described in
Section 11.6. The secondary interrupt bit is defined in Table 68.
The secondary interrupt can be masked. When the mask bit is set, the corresponding interrupt event
is masked and does not trigger an ON_PIN_INT interrupt. The secondary interrupt bit in R16401
(4011h) is valid regardless of whether the mask bit is set. The secondary interrupt is masked by
default.
