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, STMPE1601 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 14.
All other second byte values will be ignored.
