7.8 Port 7
7.8.1 Overview
Port 7 is an 8-bit input port that also provides the analog input pins for the A/D converter and
analog output pins for the D/A converter. The pin functions are the same in all modes. Figure 7.15
shows the pin configuration of port 7.

P7₇ (input)/AN₇ (input)/DA₁ (output)*
P7₆ (input)/AN₆ (input)/DA₀ (output)*
P7₅ (input)/AN₅ (input)
P7₄ (input)/AN₄ (input)
P7₃ (input)/AN₃ (input)
P7₂ (input)/AN₂ (input)
P7₁ (input)/AN₁ (input)
P7₀ (input)/AN₀ (input)
Note: * The DA₁ and DA₀ pin functions apply to the H8/3337 Series only.
The H8/3397 Series does not have an on-chip D/A converter, and therefore has no DA₁
and DA₀ pin functions.
