Functions

Order

STB ports in the state by the high-low, the importation of an order by the DIN port of the first byte (b0 ~ b7). If

the data or the order in the transmission For some reason, STB is set to port, serial communications are to be

initialized, the data is input / command be considered invalid.

Order 1: display mode command set

ET6202 provides as follows two display modes: a command in the port of the STB by the state after the high-low

by the DIN port to lose ET6202 into the first byte (b0 ~ b7). For these orders, the No. 3 to No. 6 (b2 ~ b5) are ig-

nored, 7 and 8 (b6 ~ b7) 0. Display mode command set used by the decision, gate number (4 to 7, 10 to 13). Must

show that an order to continue to make the show. If you choose the same mode settings, not to implement the

order, so there will be no show. When the electric power, the choice of 10 × 7-bit mode.

Order 2: Set the order data

Data set is the order of implementation of the ET6202 read and write data. The first order of 5 and 6 (b4, b5) are

ignored, 8-bit (b7) 0, No. 7 (b6) is set to 1. When the electric power supply when the first 4 to a (b3 ~ b0) should
