(1) Port mode
P100 to P106 function as an I/O port. P100 to P106 can be set to input or output port in 1-bit units using port mode
register 10 (PM10).
(2) Control mode
P100 to P106 function as serial interface data I/O and clock I/O. These pins also function as A/D converter analog
input and timer I/O.
(a) ANI20
This is an analog input pin (ANI20) of A/D converter.
When using this pin as analog input pin, see Figure 11-46. Analog Input Pin Connection.
(b) TI06, TI14 to TI17
These are the pins for inputting an external count clock/capture trigger to 16-bit timers 06, 14, 15, 16, and 17.
(c) TO06, TO14 to TO17
These are the timer output pins of 16-bit timers 06, 14, 15, 16, and 17.
2.2.12 P110 to P117 (port 11)
P110 to P117 function as an I/O port. These pins also function as A/D converter analog input.
Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 11 (PU11).
When the P115 to P117 pins are used as input, specify them as either digital or analog in Port mode control register 11
(PMC11). This register can be specified in 1-bit unit.
The following operation modes can be specified in 1-bit units.
(1) Port mode
P110 to P117 function as an I/O port. P110 to P117 can be set to input or output port in 1-bit units using port mode
register 11 (PM11).
(2) Control mode
P110 to P117 function as A/D converter analog input.
(a) ANI24 to ANI26
These are the analog input pins (ANI24 to ANI26) of A/D converter.
When using this pin as analog input pin, see Figure 11-46. Analog Input Pin Connection.
2.2.13 P120 to P127 (port 12)
P120 and P125 to P127 function as an I/O port. P121 to P124 functions as 4-bit input port. These pins also function
as A/D converter analog input, connecting resonator for main system clock, connecting resonator for subsystem clock,
external clock input for main system clock, and external clock input for subsystem clock.
P120, P125 to P127 use of an on-chip pull-up resistor can be specified by pull-up resistor option register 12 (PU12).
When the P120 pin is used as input, specify them as either digital or analog in Port mode control register 12 (PMC12).
This register can be specified in 1-bit unit.
The following operation modes can be specified in 1-bit units.
