AVDD0
−
−
<When one or more of P20 to P27, P150 to P152, or P157 are
set as a digital port>
Make this pin the same potential as EVDD or VDD.
<When all of P20 to P27, P150 to P152, and P157 are set as
analog ports>
Make this pin to have a potential where 2.3 V ≤ AVDD0 ≤ VDD.
AVDD1
−
−
<When one or more of P110 or P111 are set as a digital port>
Make this pin the same potential as EVDD or VDD.
<When all of P110 and P111 are set as analog ports>
Make this pin to have a potential where 2.3 V ≤ AVDD1 ≤ VDD.
AVSS
−
−
Make this pin the same potential as the EVSS or VSS.
VREFOUT/AVREFP
−
−
Make this pin the same potential as the AVDD0, EVDD or VDD.
FLMD0
2-W
−
Leave open or connect to VSS via a resistor of 100 kΩ or more.
RESET

Notes 1.
2.
3.
P150/ANI8/AMP2+ to P152/ANI10 and P157/ANI15/AVREFM are set in the digital input port mode after release
of reset.
AVREFM applies to μ PD78F150xA only.
μ PD78F151xA corresponds to type 11-G.
