This register contains status information indicating when counter data has been
transferred into holding registers and indicating whether the holding registers
have been overrun. Configuration for PMON interrupt enable is also available in
this register.
INTE:
The INTE bit controls the generation of a microprocessor interrupt when the
transfer clock has caused the counter values to be stored in the holding
registers. A logic 1 bit in the INTE position enables the generation of an
interrupt ; a logic 0 bit in the INTE position disables the generation of an
interrupt.
XFER:
The XFER bit indicates that a transfer of counter data has occurred. A logic 1
in this bit position indicates that a latch request, initiated by writing to one of
the counter register locations, was received and a transfer of the counter has
occurred. A logic 0 indicates that no transfer has occurred. The XFER bit is
cleared (acknowledged) by reading this register.
OVR:
The OVR bit is the overrun status of the holding registers. A logic 1 in this bit
position indicates that a previous interrupt has not been acknowledged before
the next transfer clock has been issued and that the contents of the holding
registers have been overwritten. A logic 0 indicates that no overrun has
occurred. The OVR bit is cleared by reading this register.
