DESCRIPTION
NO.
CLKOUT4/GP1
AE6
CLKOUT4
GP1EN = 0 (disabled)
These pins are software-configurable.
To use these pins as GPIO pins, the
GPxEN bits in the GPIO Enable
Register and the GPxDIR bits in the
GPIO Direction Register must be
properly configured.
GPxEN = 1: GPx pin enabled
GPxDIR = 0: GPx pin is an input
GPxDIR = 1: GPx pin is an output
CLKOUT6/GP2
AD6
CLKOUT6
GP2EN = 0 (disabled)
GP9/PIDSEL
M3
needs to be disabled (PCI_EN = 0), the
GPxEN bits in the GPIO Enable
Register and the GPxDIR bits in the
GPIO Direction Register must be
properly configured.
GPxEN = 1: GPx pin enabled
GPxDIR = 0: GPx pin is an input
GPxDIR = 1: GPx pin is an output
GP10/PCBE3

To use GP[15:9] as GPIO pins, the PCI

GPxEN = 0 (disabled)
PCI_EN = 0 (disabled)

By default, HPI is enabled upon reset
(PCI is disabled).
To enable the PCI peripheral an external
on the PCI_EN pin (setting PCI_EN = 1
at reset and keeping valid “1” after
reset).

CLOCK/PLL CONFIGURATION
CLKIN

I
IPD
Clock Input. This clock is the input to the
on-chip PLL.
CLKOUT4/GP1§
AE6
I/O/Z
IPD
Clock output at 1/4 of the device speed
(
O/Z
) [default] or this pin can be pro-
grammed as a GPIO 1 pin (
I/O/Z
).
CLKOUT6/GP2§
AD6
I/O/Z
IPD
Clock output at 1/6 of the device speed
(
O/Z
) [default] or this pin can be pro-
grammed as a GPIO 2 pin (
I/O/Z
).
All other standalone PCI pins are tied-off internally (pins in Hi-Z) when the peripheral is disabled [PCI_EN = 0].
For the HD[31:0]/AD[31:0] multiplexed pins pin numbers, see the
Terminal Functions
table.
