1. External PNP regulator has a higher regulation point to ensure that the current flows through the PNP when the application
fails to disable the internal regulator byclearing INTXON.
2. Please note that the core current is derived from VDDX
3. Further limitation may apply due to maximum allowable T
J
4. Maximum load current depends on the current gain of the external PNP and available base current
5. LVI is monitored on the VDDA supply domain
6. LVRX is monitored on the VDDX supply domain only active during full performance mode. During reduced performance mode
(stop mode) voltage supervision is solely performed by the POR block monitoring core VDD.
7. For the given maximum load currents and V
SUP
input voltages, the MCU will stay out of reset.
8. The ACLK trimming must be set that the minimum period equals to 0.2ms
9. VREGHTTR=0x88
10. This is the minimum base current that can be guaranteed when the external PNP is delivering maximum current.

Note: VDDA and VDDX must be shorted on the application board.
