8.7.4
Port 6 has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in any operating mode, and can be specified as on or off on a
bit-by-bit basis.
When a P6DDR bit is cleared to 0, setting the corresponding KMPCR bit to 1 turns on the MOS
input pull-up for that pin. The MOS input pull-up current specification can be changed by means
of the P6PUE bit. When a pin is designated as an on-chip supporting module output pin, the MOS
input pull-up is always off.
The MOS input pull-up function is in the off state after a reset and in hardware standby mode. The
prior state is retained in software standby mode.
Table 8.16 summarizes the MOS input pull-up states.

Selection Method and Pin Functions
This pin is used as the FTCI input pin when an external clock is selected with
bits CKS1 and CKS0 in TCR of the FRT.
It can always be used as the TMIX, KIN0, CIN0, or HFBACKI input pin.
