Questions answered in these manuals

What is the function of the Low Power Voltage Regulator (LPVR)?

The LPVR provides a power supply of about 1.8V when the Main Voltage Regulator is switched off during low-power modes.

From: ST AN2202 Application Note

How can the Main Voltage Regulator (MVR) be switched off?

The MVR can be switched off when entering a low power mode by setting the VRLPW bit in the PRCCU_VRCTR register.

From: ST AN2202 Application Note

What condition enters the STR73x into SystemMemory Boot Mode?

The device enters this mode if the mode pins are configured with M0=0, M1=1 as the hardware reset pin transitions High at the end of a hardware reset.

From: STMicroelectronics AN2260 STR73x SystemMemory Boot Mode Application Note

What is the minimum baud rate for UART booting at 12MHz?

The minimum baud rate determined by the maximum count capacity of Timer Base 0 when measuring the zero byte is 1648, with the lowest standard Baud Rate being 2400.
