a. V_DD-A = V_DD-C = 2.5V, V_DD-IO = 3.0V
I_DDA = ¦{I_DD-IO+ I_DD-C + I_DD-A}, f_CLK = 24MHz at 30 fps, no I/O loading
b. V_DD-A = V_DD-C = 2.5V, V_DD-IO = 3.0V
I_DDS:SCCB refers to a SCCB-initiated Standby, while I_DDS:PWDN refers to a PWDN pin-initiated Standby
c. Standard Output Loading = 25pF, 1.2K: to 3V
