NOTE
• PTC7-PTC0 and PTA7-PTA6 are not available on 16-pin Packages
• PTC7-PTC4 and PTA7-PTA6 are not available on 20-pin Packages
• For the 16-pin and 20-pin packages: V_DDA/V_REFH and V_SSA/V_REFL are
double bonded to V_DD and V_SS respectively.
Δ = Pin can be enabled as part of the ganged output drive feature
