Length of MAC, BBP and RF registers

[Ronak Chokshi]

Hi Marcelo,
The lengths of registers stated by Javier are correct. For your other
question, the size of the EEPROMs used on the USB 8388 parts shipped
with the OLPC boards is indeed 16K. The contents keep changing with any
boot2 / calibration changes that we make but the size is constant - 16K.
This is the actual size of the EEPROM hardware. The contents are smaller
than 16K.

Thanks
Ronak

Marcelo,

This is what I could find out:

These commands each access a different bank of registers, the offset
parameter determines which
register.

BBP, band pass processor registers, uint8.
RF, RF PHY registers, uint8.
MAC, MAC registers, uint32.

Hope it helps.
