Description
Crystal type select: "0" or floating. select 32.768KHz crystal. "1" select 3.58MHz
resonator.
There are 8 or 7 bits in each data byte.
Using parallel-in and serial-out components, the data bytes are shifted out from bit 0
through the high bits. SC83702 will transmit the data while the status of three key
switches or the state of the horizontal counter or vertical counter is changed.
