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.

Note:

All other second byte value will be ignored.

Table 15.

R/W

Second byte value

Definition

0x06

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.

0x04

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.

0x00

Not allowed as second byte.
