C Bus Protocol
The sequence is as follows:
– Initial condition: a Write is in progress (see Figure
7).
– Step 1: the master issues a START condition
followed by a device select byte (1st byte of the
new instruction).
– Step 2: if the memory is busy with the internal
write cycle, NoACK will be returned and the
master goes back to Step 1. If the memory has
terminated the internal write cycle, it will respond
with an ACK, indicating that the memory is ready
to receive the second part of the incoming in-
struction (the first byte of this instruction was
already sent during Step 1).
Set the Protection using the Protect Register.
The M34W02 has a software write protection func-
tion, with the use of a Protect Register, that allows
a selectable memory area size to be defined as
write protected. To activate the write protection
feature, an address pointer has to be written into
the Protect Register. When write protected by the
Protect Register and the WC pin, the selected
memory area will behave as a ROM area.
The Protect Register is accessed by sending a
write command with the 4 device type identifier bits
of the device select code set to 0110b (see Figure
9), the E2-E1-E0 bits as applied on the E2-E1-E0
pins and regardless of the state of the WC signal.
