FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
RESETS
The 908E621 has four internal and one external reset
source.
Each internal reset event will cause a reset pin low for t
RST
(1.25 ms typical), after the reset event is gone.
Figure 15. Internal Reset Routing
RESET SOURCE
High Temperature Reset
The device is protected against high temperature. When
the chip temperature exceeds a certain temperature, a reset
(HTR) is generated. The reset is flagged by bit HTR in the
Interrupt Flag Register. A HTR event will reset all registers in
the SPI excluding the RSR.
The HTR can be disabled by bit HTRD in the Interrupt
Mask register.
Note: Disabling the high temperature reset can lead to
destruction of the part in cases of high temperature. This
bit was foreseen for test purposes only!
Watchdog Reset
The WatchDog module generates a reset, because of a
watchdog time-out or wrong watchdog timer reset. Reset is
flagged by bit WDR in the Reset Status Register. A Watchdog
reset event will reset all registers in the SPI excluding the
RSR.
Main VREG Low Voltage Reset
The LVR is related to the Main VDD. In case the voltage
falls below a certain threshold, it will pull down the RST_A
terminal. Reset is flagged by bit LVR in the Reset Status
Register. A LVR event will reset all register in the SPI
excluding the RSR.
Power On Reset
The POR is related to the internal 5V supply. In case the
device detects a power on the POR bit in the Reset Status
Register (RSR) is set. A power on reset will reset all register
in the SPI including the RSR and set the POR bit.
The Power On Reset circuitry will force the RST_A
terminal low for t
RST
after the V
DD
has reached its nominal
value (above LVR Threshold).

).
Reset terminal / external Reset
An external reset can be applied by pulling down the
RST_A terminal. The reset event is flagged by bit PINR in the
reset status register.
Reset Status Register
This register contains five flags that shows the source of
the last reset. A power-on reset sets the POR bit and clears
all other bits in the Reset Status Register. All bits can be
cleared by writing a one to the corresponding bit. Uncleared
bits remain set as long as they are not cleared by a power-on
reset or by software.
