6.9 Concurrent Touch Handling
It has concurrent touch handling function which can distinguishes the intended key(s) from concurrently touched keys.
There are the following four cases, first touched, last touched, both and deeply touched, according to the option parameter.

6. 11 Reset
We use the internal reset circuit, which reset the entire chip when the power (VDD) is on [POR],
It reset the chip when VDD go over 1,5V automatically.
When SOFTRES command is inputted, All Registers are set Default

6. 12 E2PROM
In power-on mode, when the Register EEP Mode is ‘H’, the register values in E2PROM are got and set to registers.
But when the Register EEP Mode is ‘L’, the default register values are set to the registers.
In programming mode you can use E2PROM as the register memory or not. When Register EEP Mode is ‘H’,
E2PROM is used. The register values from host are saved in E2PROM and at the same time set to registers.
When EEP is ‘L’, the register values from host are set to registers directly.
