Enable interrupt support in PCA_SERIES driver.

Note that the PCA_SERIES cannot reliably detect

short-pulse interrupts due to its design.

Cache all registers in RAM for faster configuration.

Enabled by default.
|

When disabled, only output registers will be cached.
|
|
|
|
|
On devices w/o interrupt status, it will also cache
|
|
|
|
|
input state.
