13.2 Timing characteristics
During communication, the KMA199 is always the slave and the external programming
hardware is the master.
The master provides the start condition, which is a rising edge after a LOW level. Then a
command byte which can be either a read or a write command is send. Depending on the
command, the master or the slave has to send the data immediately after the command
sequence. In the case of a read command, an additional handover or takeover bit is
inserted before and after the data bytes. Each communication must be closed with a stop
condition driven by the master. If the slave does not receive a rising edge for a time longer
than t
condition and a new command. This can be used to synchronize the device regardless of
the previous state.
All communication is based on this structure (see
command mode. In this case a special write command is required, followed by the
command sequence (two data bytes). The customer can access the EEPROM, CTRL1,
TESTCTRL0 and SIGNATURE registers (described in
reset will leave the command mode. A more detailed description of the programming is
given in the next sections.
As described in the previous section, a start and stop condition is necessary for
communication. The LOW-level duration before the rising edge of the start condition is
defined as t
