CHAPTER 9 I/O PORT
Operation of the input level selection register
• Writing "1" to the bit6 of ILSR2 changes Port 9 from the hysteresis input level to the automotive input
level. When the bit6 of ILSR2 is "0", it should be the hysteresis input level.
Table 9.7-4 shows the pin states of the port

*: "Input enabled" means that the input function is enabled; it requires the pull-up or pull-down operation, or preventing
leaks by external inputs. Same as other ports when used as an output port.
