ST7565S
V
é³ is set to 1 level of 64 possible levels by the electronic volume function depending on the data set in the 6-bit electronic
volume registers. Table 10 shows the value for é depending on the electronic volume register settings.
Rb/Ra is the V
internal resistor ratio set command. The (1 + Rb/Ra) ratio assumes the values shown in Table 11 depending on the 3-bit data
settings in the V
V
Figures 9, 10 show V
volume resister for each temperature grade model.
