Output: Leave open.
Notes 1. 48-pin products only
2.
μ PD78F0586, 78F0587, and 78F0588 (products with operational amplifier) only
3. If this pin is left open when specified as an analog input pin, the input voltage level might become undefined. It
is therefore recommended to leave this pin open after specifying it as a digital output pin.
4. 44-pin and 48-pin products only
Caution ANI0/P20/AMP0-, ANI1/P21/AMP0OUT/PGAIN, ANI2/P22/AMP0+, and ANI3/P23 to ANI7/P27 are set in the
analog input mode, P10/ANI8/AMP1-/SCK10, P11/ANI9/AMP1OUT/SI10, and P12/ANI10/AMP1+/SO10 are
set in the digital input mode after release of reset.
Remark Functions in parentheses ( ) in the table above can be assigned by setting the port alternate switch control
register (MUXSEL).
