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
terminal “L” level and making the value of an internal register data.
5.2
The Cautions at the Time of Using IFOK Terminal
The timing which outputs IFOK signal is the signal which shows whether the command received
from the microcomputer was performed normally.
Since the initial value of IFOK signal is unfixed when a control microcomputer is checking IFOK
signal, before sending a command, it may stop performing control from a microcomputer.
5.3
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.
5.3.1 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 command was carried out, or rewriting has been completing using IFOK signal.
5.3.2 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 reset up to interrupt before completing rewriting of data in
the rewriting processing.
5.3.3 Please do not Perform Continuation Transmission Over the 0
th Address.
The transmission over the 0th address may incorrect-operate.
The same of this restriction is said not only of ACMP mode but continuation transmission of usual
RAM data.
For example, when writing in 1B8h from 1BFh and 007h from 000h or CRAM, it must transmit in
two steps.
5.4
The Handling of NC Terminal
Please use NC terminal by either of the following.
31 pin and 37 pin
Open (non-connection)
Connect to VDD
Connect to GND
81 pin
Open (non-connection)
