NOTE
Software sets the values. Use different software in the GMSA processor to
redefine the values.
7.1.22
SCLK[0:2] Registers (PX_SCLK[0:2])
The SCLK[0:2] registers control the 24-bit configuration word of the ICS307 system clock generator.
Figure 43. SCLK[0:2] Register (PX_SCLK[0:2])
7.1.23
Watchdog Register (PX_WATCH)
The watchdog register selects a watchdog timer event for the VELA-controlled sequencer. The selected
watchdog works independently of other watchdog timers; for example, those within P5040/P5020.

WORD
• R - Returns current programmed values.
• W - WORD-written values are driven into ICS307 during reset sequencing
if PX_VCFGEN0[SCLK]=1. Otherwise, the encoded value of
CFG_SYSCLK(0:2) is used.
