• Manufacturer Part Number: ST72T311
• Description: 8-BIT MCU WITH 8 TO 16K OTP/EPROM
• Manufacturer: ST Microelectronics

SERIAL PERIPHERAL INTERFACE (Cont’d)
4.5.5 Low Power Modes
4.5.6 Interrupts
Note: The SPI interrupt events are connected to
the same interrupt vector (see Interrupts chapter).
They generate an interrupt if the corresponding
Enable Control Bit is set and the I-bit in the CC reg-
ister is reset (RIM instruction).
WAIT
HALT
SPI End of Transfer Event
Master Mode Fault Event
Mode
No effect on SPI.
SPI interrupt events cause the device to exit from WAIT mode.
SPI registers are frozen.
In HALT mode, the SPI is inactive. SPI operation resumes when the MCU is woken up by an interrupt with
“exit from HALT mode” capability.
