==0x1EC41008 and 0x1EC4100C==
== PDN_SPI_CNT ==
Bit0-3: Enable SPI bus.
== PDN_SHAREDWRAM_32K_DATA ==
Used for mapping 32K chunks of shared WRAM for DSP code.
0-1 Master (0=ARM9?, 1=ARM11?, 2 or 3=DSP/code)
2-4 Offset (0..7) (slot 0..7) (LSB of address in 32Kbyte units)
5-6 Not used (0)
7 Enable (0=Disable, 1=Enable)

==PDN_WIFI_CNT==
Bit0: Enable wifi.
==PDN_HID_CNT==
Bit0: Enable [[HID Registers]].
==PDN_TWLMODE==

Writing 0x8000 to here from the ARM9 with NATIVE_FIRM running doesn't seem to do anything, other reg-pokes likely need done first.

The following is the only time the ARM11 CODEC module uses any 0x1EC41XXX registers. In one case CODEC module clears bit1 in register 0x1EC41114, in the other case CODEC module sets bit1 in registers 0x1EC41114 and 0x1EC41116.
==PDN_CODEC_CNT==
This is the power register used for the [[PDN_Services|PDN]] CODEC service.
