Notes 1. ANIx is provided to the μPD78F041x only.
2. P20/SEG21/ANI0 to P25/SEG16/ANI5 are set in the digital input mode after release of reset.
3. With μPD78F040x, independently connect to VDD or VSS via a resistor.
Remark The functions within arrowheads (< >) can be assigned by setting the input switch control register (ISC).
