FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
RESET INTERNAL SOURCES
Autonomous Watchdog
AWD modules generates a reset because of a timeout
(watchdog function).
High-Temperature Reset
To prevent damage to the device, a reset will be initiated if
the temperature rises above a certain value. The reset is
maskable with bit HTRE in the Reset Mask Register. After a
reset the high-temperature reset is disabled.
Low-Voltage Reset
The LVR is related to the internal V
DD
. In case the voltage
falls below a certain threshold, it will pull down the
RST_A
terminal.
High-Voltage Reset
The HVR is related to the external V
SUP
voltage. In case
the voltage is above a certain threshold, it will pull down the
RST_A
terminal. The reset is maskable with bit HVRE in the
Reset Mask Register. After a reset the high-voltage reset is
disabled.
RESET
EXTERNAL SOURCE
External
Reset Terminal
The microcontroller has the capability of resetting the
SMARTMOS
device by pulling down the
RST
terminal.
Reset Mask Register (RMR)
TTEST
—
High-Temperature Reset Test
This read / write bit is for test purposes only. It decreases
the overtemperature shutdown limit for final test. Reset clears
the HTRE bit.
1 = Low-temperature threshold enabled.
0 = Low-temperature threshold disabled.
HVRE
—
High-Voltage Reset Enable Bit
This read / write bit enables resets on high-voltage
conditions. Reset clears the HVRE bit.
1 = High-voltage reset enabled.
0 = High-voltage reset disabled.
HTRE
—
High-Temperature Reset Enable Bit
This read / write bit enables resets on high-temperature
conditions. Reset clears the HTRE bit.
1 = High-temperature reset enabled.
0 = High-temperature reset disabled.
SERIAL PERIPHERAL INTERFACE
The serial peripheral interface (SPI) creates the
communication link between the microcontroller and the
908E626.
The interface consists of four terminals (see
Figure 10
):
SS
— Slave Select
MOSI — Master-Out Slave-In
MISO — Master-In Slave-Out
SPSCK — Serial Clock (maximum frequency 4.0 MHz)
A complete data transfer via the SPI consists of 2 bytes.
The master sends address and data, slave system status,
and data of the selected address.
