SoC Status and Control Register (CRP_SOCSC)
The CRP_SOCSC register contains:
•
LVI interrupt flags
•
LVI interrupt enables
•
LVI reset enables
•
LVI lock bit
SLP12EN
SLP12EN Sleep 1.2V Enable. The SLP12EN bit enables the use of the 1.2V internal regulator during Sleep
mode instead of the default 1.5V internal regulator for the VDD supply.
0 Sleep 1.2V regulator disabled during Sleep mode.
1 Sleep 1.2V regulator enabled during Sleep mode.
RAMSEL
RAM Selects. The RAMSEL bits select which ram configuration retains power during the sleep mode.
000 All RAMs powered down
001 8K RAM retains power (0x4000_0000 - 0x4000_1FFF)
010 16K RAM retains power (0x4000_0000 - 0x4000_3FFF)
011 32K RAM retains power (0x4000_0000 - 0x4000_7FFF)
110
64K RAM retains power (0x4000_0000 - 0x4000_FFFF)
111
80K RAM retains power (0x4000_0000 - 0x4001_3FFF)
Other
reserved (defaults to 80K on MPC5510).
PWKSRIE[0:7] Pin Wakeup Source Interrupt Enable. The PWKSRIE bits enable interrupt requests to the system if the
corresponding PWKSRCF bit is asserted. (Note: PWKSRIEn = WKPSELn, n = 0 to 7.)
0 Wakeup source interrupt disabled
1 Wakeup source interrupt enabled
