TFE-4/RV-1
TF4 Technical Information

Flash Identifiers.

Due to that DCT4 supports many different manufacturers; NMP needs to have so called
flash identifiers. The flash identifier tells the MCU which HW environment it is working
in, and also block size and configuration of the flash.
First Word.
The word contains the information about the number of flash devices connected to the
UPP. It is possible to setup the UPP so that it supports two devices. The MSB bit in the
word indicates the amount of flash devices used by the baseband. The amount of wait
states for the random access is specified over 3-bits in this word. The amount of wait
states is specified related to the system clock used in that system. The MCU PLL factor is
also specified in this word (2-bits).
Second Word.
This word contains information about flash sectors available for EEPROM emulation. If
no RWW capability is indicated, this field then contains information of the serial
EEPROM that is used in the system.
Third Word.
This word contains similar information as the first word but for the second flash if such
is used.
Fourth Word.
This word contains information about the sector configuration of the second flash.
Fifth Word.
This word contains information of the external SRAM if it is available on the baseband,
the size of it and the amount of wait states to be used when accessing it.

Audio

Within TFE-4/RV-1 the Audio signaling is realized as follows:
On the Phone Engine the Digital Signal Processor is within the UPP. It is linked to the
Codec, that is inside of the UEM, via digital serial Audio-Bus.
There are two analog signals for Microphones and one signal for the speakers going out
of the Codec, which will go over the Engine Audio Filter to the B2B connector. On the
Junctionboard the Speaker amplifier is selected by the UPP-MCU pins HDMute or
HFMute, which are also linked over the B2B connector.
