CHAPTER 4 PORT FUNCTIONS
Notes 1.

μPD78F041x only.
The functions of the P20/ANI0 to P25/ANI5 pins are determined according to the settings of port
function register 2 (PF2), A/D port configuration register 0 (ADPC0), port mode register 2 (PM2),
analog input channel specification register (ADS).

3. When using the P121 to P124 pins to connect a resonator for the main system clock (X1, X2) or
subsystem clock (XT1, XT2), or to input an external clock for the main system clock (EXCLK), the X1
oscillation mode, XT1 oscillation mode, or external clock input mode must be set by using the clock
operation mode select register (OSCCTL) (for details, see 5.3 (1) Clock operation mode select
register (OSCCTL) and (3) Setting of operation mode for subsystem clock pin). The reset value
of OSCCTL is 00H (all of the P121 to P124 are Input port pins).
4. Targeted at registers corresponding to each port.
5. RxD6 can be set as the input source for TI000 by setting ISC1 = 1.
6. Input enable of TM52 via TMH2 can be controlled by setting ISC2 = 1.
7. RxD6 can be set as the input source for INTP0 by setting ISC0 = 1.
8. When the P40/KR0/VLC3 pin is set to the 1/4 bias method, it is used as VLC3. When the pin is set to
another bias method, it is used for the port function (P40) or the key interrupt function (KR0).
9. Set PF13 = 0 when using as port function.

2. The functions within arrowheads (< >) can be assigned by setting the input switch control register
(ISC).
3. X1, X2 pins can be used as on-chip debug mode setting pins (OCD0A, OCD0B) when the on-chip
debug function is used. For detail, see CHAPTER 25 ON-CHIP DEBUG FUNCTION.
