In summary, both configuration spaces have unique registers except for the Device ID, Vendor ID, and Revision
ID, which are shared between the configuration spaces for Functions 0 and 1.
MUSYCC is a multifunction device with two sources of interrupts: the HDLC controller interrupts and the expansion
bus physical layer interrupts. MUSYCC uses the INTA* pin for HDLC controller interrupts and the INTB* pin for
interrupts generated by devices on the expansion bus connected to the EINT* pin.
All writable bits in the configuration space are reset to 0 by the hardware reset, PRST* asserted. After reset,
MUSYCC is disabled and responds only to PCI configuration write and PCI configuration read cycles. Write cycles
to reserved bits and registers have no effect. Read cycles to reserved bits always result in 0 being read.

2.2.1
MUSYCC provides the necessary configuration space for a PCI bus controller to query and configure MUSYCC’s
PCI interface. PCI configuration space consists of a device-independent header region (64 bytes) and a device-
dependent header region (192 bytes). MUSYCC provides the device-independent header section only. Access to
the device-dependent header region results in 0s being read, with no effect on writes.
There are three types of registers available in MUSYCC:
1. Read-Only (RO): Returns a fixed bit pattern if the register is used, or a 0 if the register is unused or reserved.
2. Read-Resettable (RR): Can be reset to 0 by writing a 1 to the register.
3. Read/Write (RW): Retains the value last written to it.
MUSYCC’s Function 0 PCI Configuration Space has 16 dword registers.
