I/O control for port P6

(specified for each bit)
#1
Do not set output mode to pin which is used for an analog input.
Note 1: When used as an
the P6 should set to "1".
Note 2: When used as an STOP2 to STOP5 pins of Key on Wake up, the respective bit of P6CR should be set to "0".
Note 3: When a read instruction for port P6 is executed, the bit of Analog input mode becomes read data "0".
Note: Although P6DR is a read/writer register, because it is also used as an input mode control function, read-modify-
write instructions such as bit manipulate instructions cannot be used.
Read-modify-write instruction writes the all data of 8-bit after data is read and modified. Because a bit setting Input
mode read data of terminal, the output latch is changed by these instruction. So P6 port can not input data.
