MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
Functional Modes
The 33742 has four modes of operation, all controlled by the
SPI. The modes are Standby, Normal, Stop, and Sleep. An
additional temporary mode called
Normal Request mode is
automatically accessed by the device after reset or wake-up
from Stop mode. A Reset mode is also implemented. Special
modes and configuration are possible for debug and program
microcontroller flash memory.
Table 2
below offers a summary of the functional modes.
Reset Mode
In the Reset mode, the
RST
terminal is LOW and a timer runs
for t
RSTDUR
time. After t
RSTDUR
has elapsed, the 33742 enters
Normal Request mode. Reset mode is entered if a reset
condition occurs (V
DD
LOW, watchdog timeout, or watchdog
trigger in a closed window).
Normal Request Mode
Normal Request mode is a temporary mode automatically
accessed by the 33742 after the Reset mode or after the 33742
wakes up from Stop mode. After wake-up from the Sleep mode
or after device power-up, the 33742 enters the Reset mode
before entering the Normal Request mode. After a wake-up
from the Stop mode, the 33742 enters the Normal Request
mode directly.
