4.1 - STA013 REGISTERS DESCRIPTION
The STA013 device includes 128 I
2
C registers. In
this document, only the user-oriented registers
are described. The undocumented registers are
reserved. These registers must never be ac-
cessed (in Read or in Write mode). The Read-
Only registers must never be written.
The following table describes the meaning of the

UPD_FRAC:when is set to 1, update FRAC in
the switching circuit. It is set to 1 after autoboot.
XTI2OCLK:when is set to 1, use the XTI as input
of the divider X instead of VCO output. It is set to
0 on HW reset.
XTI2DSPCLK: when is to 1, set use the XTI as in-
put of the divider S instead of VCO output. It is
set to 0 on HW reset.
PLLDIS: when set to 1, the VCO output is dis-
abled. It is set to 0 on HW reset.
SYS2OCLK:when is set to 1, the OCLK fre-
quency is equal to the system frequency. It is
useful for testing. It is set to 0 on HW reset.
OCLKEN: when is set to 1, the OCLK pad is en-
able as output pad. It is set to 1 on HW reset.
XTODIS: when is set to 1, the XTO pad is dis-
able. It is set to 0 on HW reset.
XTO_BUF: when this bit is set, the pin nr. 28
(OUT_CLOCK/DATA_REQ) is enabled. It is set
to 0 after autoboot.

The M and N registers are used to configure the
STA013 PLL by DSP embedded software.
M and N registers are R/W type but they are
completely controlled, on STA013, by DSP soft-
ware.
