MSM9225
24/73
9. Standby control register (STBY: 8Ehex)
This register sets various modes, such as stop mode.
The bit configuration is as follows:
76543210
Address MSB
8Eh
LSB
STOP : Stop mode
SLEEP : Sleep mode
Not used
(1) Stop mode: STOP
If STOP is set to "1", the MSM9225 will enter the stop mode when the CAN bus is idle.
In stop mode, the content of data memory is held but the oscillator and all circuits stop
to save power consumption. Access to/from external units is therefore disabled.
Stop mode is cleared by a reset signal input from the RESET pin or CS pin = "0".
At reset, STOP is set to "0".
(2) Sleep mode: SLEEP
If SLEEP is set to "1", the MSM9225 will enter the sleep mode when the CAN bus is idle.
In sleep mode, the content of data memory is held and the differential input of Rx0 and
Rx1 operates, but the oscillator and other circuits stop operation. Access to/from
external units is therefore disabled.
Sleep mode is cleared by a reset signal input from the RESET pin or CS pin = "0", or by
the differential input of Rx0 and Rx1.
When both stop mode and sleep mode are set at the same time, the MSM9225 enters stop
mode.
At reset, SLEEP is set to "0".
