4.30 Multifunction Routing Register
The multifunction routing register is used to configure the MFUNC0–MFUNC6 terminals. These terminals may be
configured for various functions. All multifunction terminals default to the general-purpose input configuration. This
register is intended to be programmed once at power-on initialization. The default value for this register may also be
loaded through a serial bus EEPROM. See Table 4–8 for a complete description of the register contents.

MFUNC6
R/W
Multifunction terminal 6 configuration. These bits control the internal signal mapped to the MFUNC6 terminal
as follows:
0000 = RSVD
0100 = IRQ4
1000 = IRQ8
0001 = CLKRUN
0101 = IRQ5
1001 = IRQ9
0010 = IRQ2
0110 = IRQ6
1010 = IRQ10
0011 = IRQ3
0111 = IRQ7
1011 = IRQ11
1100 = IRQ12
1101 = IRQ13
1110 = IRQ14
1111 = IRQ15
23–20
MFUNC5
R/W
Multifunction terminal 5 configuration. These bits control the internal signal mapped to the MFUNC5 terminal
as follows:
0000 = GPI4
0100 = IRQ4
1000 = CAUDPWM
0001 = GPO4
0101 = RSVD
1001 = IRQ9
0010 = PCGNT

1101 = LED_SKT
1110 = GPE
1111 = IRQ15
19–16
MFUNC4
R/W
Multifunction terminal 4 configuration. These bits control the internal signal mapped to the MFUNC4 terminal
as follows:
NOTE: When the serial bus mode is implemented by pulling up the VCCD0 and VCCD1 terminals, the
MFUNC4 terminal provides the SCL signaling.
0000 = GPI3
0001 = GPO3
0010 = LOCK PCI
0011 = IRQ3
0100 = IRQ4
0101 = IRQ5
0110 = ZVSTAT
0111 = ZVSEL0
1000 = CAUDPWM
1001 = IRQ9
1010 = IRQ10
1011 = IRQ11
1100 = RI_OUT
1101 = LED_SKT
1110 = GPE
1111 = IRQ15
15–12
MFUNC3
R/W
Multifunction terminal 3 configuration. These bits control the internal signal mapped to the MFUNC3 terminal
as follows:
0000 = RSVD
0100 = IRQ4
1000 = IRQ8
0001 = IRQSER
0101 = IRQ5
1001 = IRQ9
0010 = IRQ2

MFUNC2
R/W
Multifunction terminal 2 configuration. These bits control the internal signal mapped to the MFUNC2 terminal
as follows:
0000 = GPI2
0100 = IRQ4
1000 = CAUDPWM
0001 = GPO2
0101 = IRQ5
1001 = IRQ9
0010 = PCREQ
0110 = ZVSTAT
1010 = IRQ10
0011 = IRQ3
0111 = ZVSEL0
1011 = IRQ11
1100 = RI_OUT
1101 = RSVD
