non-selecting periods when ROWRES2 is HIGH; 1.25 to 2.0 V referred to V
outputs
row outputs
LCD row outputs
clock input to the shift register; data is transmitted with the positive clock
edge; connect RCLK to the RCLK output of the PCF8832 column driver
row pulse input; driven by the RP output of the PCF8832 column driver
frame inversion input; controls frame and N-line inversion; FI is synchronized
internally by the rising edge of RCLK; FI can change only when RP changes;
connect FI to the FI output of the PCF8832 column driver
input that switches the non-selected level (V
ROWRES2) to all row outputs; connect SVM to the SVM output of the
PCF8832 column driver
external reset input 1; when LOW, the shift register is reset at the next rising
edge of RCLK and all outputs (R0 to R159) go to their non-selected level;
connect ROWRES1 to the RESROW output of the PCF8832 column driver
external reset input 2; when LOW, the non-selected level goes to V
HIGH, the non-selected level goes to V
RESROW output of the PCF8832 column driver
inputs R1F (row block 1 first), SW1 (swap row block 1) and SW2 (swap row
block 2) control the shift direction through the register and the order of the
register; see Table 1; connect to the corresponding signal outputs of the
PCF8832 column driver, or connect directly to V
display module configuration
test inputs; connect to V
logic power supply, negative; normally connected to system ground
logic power supply, positive; 2.4 to 3.5 V referred to V
MID-level LCD driving voltage; level is between V
auxiliary supply voltage for row switch; higher than V
HIGH-level LCD driving voltage; top level of the positive selecting pulse of row
LOW-level LCD driving voltage; bottom level of the negative selecting pulse of
