Note:
General call address
A general call address is a transaction with the slave address of 0x00 and R/W =0. When a
general call address is asserted, the STMPE1801 responds to this transaction with an
acknowledgement and behaves as a slave-receiver mode. The meaning of a general call
address is defined in the second byte sent by the master-transmitter.
Table 10.
All other second byte values are ignored.

A 2-byte transaction in which the second byte tells the slave device to reset
and write (or latch in) the 2-bit programmable part of the slave address.
Not allowed as second byte.
