The PCF50606 is the Power Management Unit used in GTA01. Apparently this unit is very popular in MP3 players, as the Rockbox project has talked a lot about writing a driver for it (but hasn't completed any, as far as we know).
Configuration of this PMU is done via an I2C bus from the S3C2410.

- Main article: Neo_1973_hardware
- Connected to: Samsung S3C2410 via I2C, client address is 0x08.
- The PMU also connects to EINT16 and thus can issue interrupts to the main CPU.
This chip is only used in the Neo1973. The Neo FreeRunner uses NXP PCF50633.

[edit] Register dump after bootup
Since u-boot has built-in I2C support for the S3C2410, we can read out the register set of the PC50606 using a simple command:
GTA01 # imd 0x08 0x00 0x3c
0000: 4d 7b 48 01 00 00 00 00 64 05 43 23 00 00 01 01 M{H.....d.C#....
