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 made, STMPE2403 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 15.
All other second byte value will be ignored.

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