8. Miscellaneous
Several other system MMIO registers are described in the following paragraphs and
detailed in the next Section 8.1:
• By default PCI_INTA_N is an input/output pin used in open drain mode for the
PCI bus. When a host CPU wants to assert an interrupt to the TM5250 it asserts
the PCI_INTA_N low. Similarly if TM5250 wants to notify a host CPU of an
interrupt it can assert low the PCI_INTA_N pin by programming the PCI_INTA
MMIO register.
• The 8 SCRATCH MMIO registers are mainly used for debug purpose. Since they
are not reset by the external POR_IN_N or RESET_IN_N signals they can be
used for post-mortem system crash to retain some critical or debug values.
• Event timestamping for the SPDI interface comes with a diversity of
requirements. To keep PNX17xx Series as a programmable system, a system
multiplexer is implemented to select which event or signal to timestamp. The
multiplexer is controlled by the SPDI_MUX_SEL MMIO register. The different
selectable signals coming from the SPDI module are displayed in Section 8.1.
• The SPARE_CTRL MMIO register is reserved for future usage.
