2. The JADE writes the firmware version number into communication register accessible
3. The host checks the INHB bit and as soon as it reads a ‘0’ it may get the version
The version number of JADE MM 2.1 is (for historical reasons) 33
picture above has to be substituted by this number.
The following steps are executed:
1. The host generates an interrupt to the JADE by writing value 19
6.1.2
A software reset (see Figure 40) is used to re-initialize the JADE without resetting the
hardware. This means that e.g. not the whole configuration/control register area is reset,
but only the firmware initialization (see Section 5.3 and Section 5.4) is executed.
