Low Power Operation on the MCF5213

Gcoakley — Sat, 10 Jun 2006 01:32:49 GMT

Hello All,

Can anyone provide any assistance on Low Power Operation on the MCF5213? I believe I have the registers (LPCR, LPICR, PPMRH, and PPMRL) set correctly, but I cannot find the "STOP instruction" mentioned in the "MCF5213 Reference Manual". Is there sample code available which illustrates Low Power Operation? Thank you.

Ok. I have found the solution myself. Thank you Freescale, it only took three days of searching through your confusing website with your poor search engine to find sample code and documentation.

Here are the links, I found.

The code example (power) also requires the following definitions.

#define stop_2700() asm(" stop #0x2700")
#define stop_2600() asm(" stop #0x2600")
#define stop_2500() asm(" stop #0x2500")
#define stop_2400() asm(" stop #0x2400")
#define stop_2300() asm(" stop #0x2300")
#define stop_2200() asm(" stop #0x2200")
#define stop_2100() asm(" stop #0x2100")
#define stop_2000() asm(" stop #0x2000")
