Name I/O Function Vertical shift data input/output pins Input/output shift data. The pin function is switched between input and output by the U/D pin as follows: U/D DI/O I/O DO/I DI/O DO/I H Input Output L Output Input At input Data are latched into the shift registers in sync with the rising edge of CPV. At output: If the JBT6L78-AS is cascade-connected, data to be input at the next stage are output from the pin. The data state changes in sync with the falling edge of CPV. U/D I Data transfer direction switching pin Specifies the shift direction of the shift registers. Data in the shift registers shift in sync with the rising edge of CPV as follows: · U/D = H: G1 ® G2® G3 ® … ® G162 · U/D = L: G162 ® G161® G160 ® … ® G1 Use the pin at DC level. For High, VDD; for Low, VSS. Note that if U/D mode is switched during data transfer, misoperation occurs to a display page. CPV I Vertical shift clock Shift clock for the shift registers. Data are shifted in sync with the rising edge of CPV. OE1 to OE3 I Output enable pin These pins control output data from the output pins (G1 to G162). · OE = L: Normal output state (1-pulse scanning) · OE = H: Outputs VOFF voltage. Note that the contents of the shift registers are not cleared. Those operations are performed asynchronously to CPV. G1 to G162 O LCD panel drive pins. I TEG Test pin. Leave the pin open.
