... I the parallel bus system to communicate bi-directionally with the 2 I C-bus. The PCA9564 can operate as a master or a slave and can be a transmitter or receiver. Communication with the I carried out on a byte-wise basis using interrupt or polled handshake. 2 The PCA9564 controls all the I C-bus specific sequences, protocol, arbitration and timing with no external timing element required ...

... ENSIO = “1”: When ENSIO is “1”, SIO is enabled. After the ENSIO bit is set, it takes 500 s for the internal oscillator to start up, therefore, the PCA9564 will enter either the master or the slave mode after this time. ENSIO should not be used to temporarily 5 ...

... Philips Semiconductors 2 Parallel bus to I C-bus controller 2 release the PCA9564 from the I C-bus since, when ENSIO is reset, 2 the I C-bus status is lost. The AA flag should be used instead (see description of the AA flag in the following text). In the following text assumed that ENSIO = “1”. ...

... While AA is reset, SIO does not respond to its own slave address. 2 However, the I C-bus is still monitored and address recognition may be resumed at any time by setting AA. This means that the AA bit may be used to temporarily isolate SIO from the I 7 Product data sheet PCA9564 ...
