PC Master Software Operation with the MC3PHAC
When power is first applied to the MC3PHAC, or if a logic low level is applied to the RESET pin, the
MC3PHAC enters PC master software mode if the VBOOST_MODE pin is low during the initialization
phase. The MC3PHAC recognizes a subset of the PC master software command set, which is listed in
Table
With the READVARx commands, the addresses are checked for validity, and the command is executed
only if the address is within proper limits. In general, a read command with an address value below $0060
or above $EE03 will not execute properly, but instead will return an invalid operation response. An

Notes:
1. If no external fault circuit is provided, connect to V
2. Use bypass capacitors placed close to the MC3PHAC.
3. Consult crystal/resonator manufacturer for component values.
