Table 86. Device Status Interrupt Mask Register
on IRQ (assert low). By default, all of the device status
interrupts (except JDET) only set the corresponding
status bit and do not generate a hardware interrupt. Set
the corresponding bit high in the mask register to enable
hardware interrupts.
Device Revision Identication
The device provides a Revision ID Number register to
allow the software to identify the current version of the
device. The current device revision ID value is 0x43.
