To keep the access time as small as possible, this format allows a read access without the word address transfer in
advance to the data transfer. The bus is idle and the master issues a START condition followed by the Device-Read
st
address. Analogous to Random-Read, a single byte transfer is terminated with a not-acknowledge after the 1 register
byte. Analogous to Sequential-Read an unlimited number of data bytes can be transferred, where the data bytes has to
be responded with an acknowledge from the master. For termination of the transmission the master sends a not-
acknowledge following the last data byte and a subsequent STOP condition.

Reset generator and XON-Key
XRESET is a low active bi-directional pin. An external pull-up to the periphery supply has to be added.
During each reset cycle the following states are controlled by the AS3658:
Pin XRESET is forced to GND
Programmable Power-off function
Programmable Power-on sequence and regulator voltages
Programmable reset timer
All registers are set to their default values after power-on, except the reset control- and status-registers.
Note: Programming is controlled by the internal Mask-PROM and the external resistor RPROGRAM
