Data Sheet
OSCPD
LCD(1:0)
Oscillator Power Down
This bit switches the internal oscillator (used if a crystal is connected to
pins XTAL1 and XTAL2) in power-down (stand-by) mode:
OSCPD=’0’
OSCPD=’1’
LBI Clock Division
The internal LBI operating clock (which is monitored on output pin
LCLKO) is internally derived from the PCI clock input pin CLK and a
clock division unit. The division factor can be selected via this bit field:
LCD = ’00’
LCD = ’01’
LCD = ’10’
LCD = ’11’
Note: The LBI clock signal monitored on pin LCLKO is an asymmetric
clock signal. The LBI clock high phase time is always equal the
PCI clock high phase time (typical 15 nano seconds). The LBI
clock low phase time is extended respectively.
Normal operation. The internal oscillator works, if a crystal
is connected to pins XTAL1 and XTAL2.
The internal oscillator is in power-down mode.
Reserved, do not use.
LCLK = CLK / 2
LCLK = CLK / 4
LCLK = CLK / 16
