H = HIGH-level output voltage
L = LOW-level output voltage
9.4 3-wire bus mode
For the 3-wire bus mode pin BUSMODE = HIGH, i.e. connected to VCCA. The pins
CLOCK, DATA and WRITE_READ are used to communicate with the external hardware
(microcontroller or PC). The bus operates at a maximum clock of 1 MHz.
The selected mode (read or write mode) is determined by the rising or falling edge of
signal WRITE_READ.
9.4.1 Write mode
At the rising edge of signal WRITE_READ the bus interface is set to the write mode. At
every rising edge of the clock input (CLOCK) the data is clocked in. Signal DATA has to be
stable before it can be clocked in.
