VI.41 - Fill Character Register 2
FC0/7
VI.42 - SDRAM Mode Register
When the microprocessor writes in this SDRAM Mode register, the SDRAM controller initializes the
SDRAM if the NINIT bit of GCR2 is at 0 .
When the microprocessor reads this register, the SDRAM controller is not affected.
Some parameters are frozen:
The option field is: Burst Read and Single Write.
The Burst Length is 4.
The burst data is addressed in sequential mode
The programmable parameters are:
LT0/1 :
The 12-bit word sent by the Multi-HDLC to initialize the SDRAM is:

In Transparent Mode M1, two messages are separated by FILL CHARACTERS and the de-
tection of one FILL CHARACTER marks the end of a message.
