Four of the seven instructions end with the transmission of
the instruction byte. The basic sequence is illustrated in
Figure 3. These two-byte instructions exchange data
between the Wiper Counter Register and one of the Data
Registers. A transfer from a Data Register to a Wiper
Counter Register is essentially a write to a static RAM. The
response of the wiper to this action will be delayed tWRL. A
transfer from the Wiper Counter Register (current wiper
position), to a Data Register is a write to non-volatile
memory and takes a minimum of tWR to complete.
Four instructions require a three-byte sequence to complete.
These instructions transfer data between the host and the
X9429; either between the host and one of the Data Registers
or directly between the host and the Wiper Counter Register.
These instructions are:
