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.

Note:

All other second byte values will be ignored.

Second byte value

Definition

0x06

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.

0x04

A 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
