Cautions on Use
5.1
Initial Reset
After a power-supply injection, once at least, please set up a required register after applying reset
which makes RST terminal “L” level and making the value of an internal register decide.
5.2
The Cautions at the Time of Using ACMP (address compare mode)
In rewriting coefficient data and offset data using ACMP mode, please do not use it the following
condition.
5.2.1 Please Do Not Transmit the Following Command before Completing Rewriting of Data.
Please do not send the following command before completing rewriting of data of CRAM or ORAM.
Please check that waiting the term after rewriting has been completed until it transmits the following
was carried out.
5.2.2 Please Do Not Include Data of an Intact Address.
Please do not include coefficient data of offset data of address which are not used by the program
under execution, into transmitting data. When data of an intact address is contained, operation in
ACMP mode cannot de ended. If the following command is transmitted in this state, RAM data will
become unfixed also by the command with the command unrelated to CRAM or ORAM.
It needs to reset and all data needs to be re-set up to interrupt before completing rewriting of data
in the rewriting processing.
5.2.3 Please Do Not Use the 0th Street of CRAM Address.
5.3
Please Do Not Perform Continuation Transmission over the 0th Address.
The transmission over the 0th address may incorrect-operate.
For example, when writing in 17Fh from 178h and 000h from 007h of CRAM, it must transmit in
two steps.
5.4
Please Do Not Set-Up a Soft Reset Command as the Data of Boot ROM.
