Reset flag. This bit is set if the user reset button has been
pressed; forcing the RSTOn input low. It is cleared by
writing to the STFClr location. On power-on-reset, it is
reset to 0b.
Test reset flag. This bit is set if the test reset has been
activated; it is cleared by writing to the STFClr location. On
power-on-reset, it is reset to 0b.
Cold start flag. This bit is set if the device has been reset
with a power-on-reset; it is cleared by writing to the STFClr
location. On power-on-reset, it is set to 1b.
Watchdog Timer flag. This bit is set if the Watchdog timer
resets the system. It is cleared by writing to the STFClr
location. It is reset to 0.
Chip ID bits. This 8-bit register determines the Chip
Identification for the device. For the device, this value is
0x20.
This 8-bit register determines the Chip Manufacturer ID for
the device. For the device, this value is 0x43.
Reserved. Unknown During Read.
