4.19. Master- and Repeater Mode
4.19.1. Master/ Repeater Mode Activation
The SAP5 Master/ Repeater Mode functionality gets enabled by use of the E²PROM flag Master_Mode (refer
to Table 9). In order to activate the Master_Mode, an IC Reset (refer to chapter 4.13 on page 43) has to be
performed after programming of the E²PROM Master_Mode flag.
For distinction between Master- and Repeater Mode the ID_Code may be set to a certain value as described
in Table 35.
NOTE: The ID_Code has to be programmed before activation of the Master_Mode flag. Once the
Master_Mode flag is set to logic HIGH, the slave functionality of the SAP5 is no longer available, preventing
any write access to the E²PROM by use of AS-i master requests as described on page 26.
Moreover, the Master- and Repeater Mode functionality may be disabled generally by use of a hidden
E²PROM flag. This flag is inaccessible by the user, but may be set during the ZMDI production test.
Table 35: Activation of the SAP5 Master/Repeater Mode
4.19.2. Pin Assignment
In Master- and Repeater Mode the SAP5 pins are configured as follows. Pins which are not used are kept at
logic HIGH (high impedance) state in order to reduce internal power dissipation of the IC.
