7-30 Freescale Semiconductor
General Purpose I/O (GPIO)
9:11 IRDA Infrared Data Association
000 = All IrDA pins are GPIOs
001 = Reserved
010 = Reserved
011 = Reserved
100 = Reserved
101 = UART (without CD) / IrDA
110 = Reserved
111 = CODEC (without MCLK) / IrDA
12: 15 Ether Ethernet
0000 = All 18 Ethernet pins are GPIOs
0001 = USB2 on Ethernet, see Note 3
0010 = Ethernet 10Mbit (7-wire) mode
0011 = Ethernet 7-wire and USB2, see Note 3
0100 = Ethernet 100Mbit without MD
0101 = Ethernet 100Mbit with MD
011X = Reserved
1000 = Ether 7-wire, UARTe, J1850
1001 = Ether 7-wire, J1850
1010 = Two UARTes, J1850
1011 = One UARTe, J1850
1100 = J1850
1101 = Reserved
111X = Reserved
16 PCI_DIS 0 = PCI controller enabled
1 = PCI controller disabled.
When Large Flash or Most Graphics modes are enabled on the localPlus bus interface, the
PCI interface can not be used (PCI control signals are used to support these modes).
When these modes are enabled (see LocalPlus control registers), the PCI controller must
be disabled to prevent interference.
If these modes are enabled at boot, this bit will come out of reset set to 1.
If these modes are not enabled at boot, this bit will come out of reset set to 0.
17 USB_SE USB Single Ended mode.
The USB interface is able to support both Differential and Single Ended modes. This bit
allows the USB I/O interface to be programmed to Single Ended mode. Differential mode
supplies TXP/TXN and RXP/TXN.
Single ended mode supplies TXP/TX_SE0 and RXP/RX_SE0.
This bit controls "all" USB ports (i.e. they are not individually programmable). Default is
Differential mode.
0 = Differential mode (Default after reset)
1 = Single ended mode
18:19 USB 00 = 4 GPIOs and 1 Interrupt GPIO
01 = USB
10 = Two UARTs
11 = Reserved
