Description
POWER UP Bit — This read-only bit indicates the last system reset was caused by the power-up
reset detection circuit.
0 Power-up reset was not the source of the reset or a read of the reset status register after the
first read.
1 The last reset was caused by an initial power-up of the MC3PHAC.
RESET PIN Bit — This read-only bit indicates the last system reset was caused from the RESET
input pin.
0 The RESET pin was not the source of the reset or a read of the reset status register after the
first read.
1 Last reset was caused by an external reset applied to the RESET input pin.
MC3PHAC FUNCTIONAL FAULT Bits — This read-only bit indicates if the last system reset was
the result of an internal system error.
FUNCTIONAL 0 The FUNCTIONAL FAULT was not the source of the reset or a read of the reset status register

reset was the result of a PC master software reset command.
0 The PC master software RESET COMMAND was not the source of the reset or a read of the
reset status register after the first read.
1 The MC3PHAC was reset by the PC master software command reset as the result of a write
of $30 to location $1000
LOW V DD VOLTAGE Bit — This read-only bit indicates if the last reset was the result of low V DD
applied to the MC3PHAC.
0 The LOW V DD was not the source of the reset or a read of the reset status register after the
first read.
1 The last reset was caused by the low power supply detection circuit.
