17.2.6 Port n Mode Register 67 (PnMOD67:n
＝
0 to 2, 4 to 9, A, B)
PnMOD67 is a special function register (SFR) to choose the input/output mode, input/output status, and shared function
of Pn6 pin and Pn7 pin.
See Table 17-2 "List of Registers / Bits" to check avaible pins and bits.
Wirte "0" to the bits of PnMOD67 register that have no corresponding pin.

This bit is used to choose the shared function of Pn7 pin.
For the details of the shared function, see Table 1-7 "ML62Q1300 Group Pin List", Table 1-8
"ML62Q1500 Group Pin List" and Table 1-9 "ML62Q1700 Group Pin List".

11 Pn7OD This bit is used choose the output type of Pn7 pin.
An LED is directly drive-able by enlarging the current when the N-channel open drain output
mode is chosen.
See the data sheet for details about the current drive ability.
0: CMOS output (initial value)
1: N-channel open drain output
