I/O serial data at rising edge of clock,

On the rising edge of the clock output
serial data, from a low starting. With DIN
shorted for DIO to use
Initialize serial port at rising/falling edge,
and then wait for receiving command.
The first byte after the STB becomes low is
taken as the command. When treating
the command, other current treatments
are stopped. When STB is high, CLK is
ignored.

Note: During data output, DIO port is N-pipe open-drain output, and when reading keys, an
external pull-up resistor of 1K – 10K is required. We recommend a 10K pull-up resistor. DIO
controls the action of the N-pipe at the falling edge of the clock, and at this time the
reading is not stable, please refer to figure (6). It becomes stable only when reading at the
rising edge of the clock.

Display register address and display mode
TM1629
The storage of this register is transferred from external component to TM1629 through serial
port, with an address of 16 bytes unit in total from 00H-ODH, corresponding to the LED lamps
connected to the chip’s SGE and GRID pin respectively. The distribution is shown as the
following figure:
When writing LED display data, operate in the order from lower position to higher position of
the display address and the data byte.
