• Manufacturer Part Number: upd161608
• Description: 176-rgb X 220-dot 1-chip Driver Ic For 262,144-color Tft-lcd Display
• Manufacturer: Renesas Electronics Corporation.

TB: Selects the output shift direction of the gate driver.
RL: Selects the output shift direction of the source driver.
Caution About TB, RL REV, and BGR function, it is initialized by the level of a hardware pin when hardware reset
TB = 0: G219 shifts to G0.
TB = 1: G0 shifts to G219.
RL = 0: Start point: S527, end point S0
RL = 1: Start point: S0, end point S527
and software reset is performed. By changing the level of the hardware pin, an internal state is also
changeable.
After sending the data of R01H by software, the data sent by software becomes valid. In this case, a
setup of a hardware pin becomes invalid until it performs hardware reset.
In addition, when TB, RL, REV, and BGR pin are changed, the timing which becomes 2 kinds valid
inside IC is as follows.
(1) About RL and TB function, these setup becomes valid inside IC in the top of a frame.
(2) About REV and BGR function, these setup becomes valid inside IC immediately.
