* Process when pins are not used
PIN TYPE “O” – Ensure that it is set to OPEN.
PIN TYPE “I” – OPEN is inhibited. Ensure that it is connected to the VDD or VSS even when it is unused.
(Please contact ON Semiconductor for more information about selection of VDD or VSS.)
PIN TYPE “B” – If you are unsure about processing method on the pin description of pin layout table, please contact us.
Note that incorrect processing of unused pins may result in defects.
* In case of connecting PORT pin with HOST CPU
When LC898217 is power off and HOST CPU is power on, a HOST CPU pin connected with PORT pin have to be fixed
"L" level.
