This bit configures the regulator’s behavior when the device enters STOP mode.
0: Regulator is still active in STOP mode. Any enabled reset source will reset the
device.
1: Regulator is shut down in STOP mode. Only the RST pin or power cycle can reset
the device.
This bit places the regulator in bypass mode, allowing the core to run directly from the
V
0: Normal Mode—Regulator is on and regulates V
1: Bypass Mode—Regulator is in bypass mode, and the microcontroller core operates
directly from the V
IMPORTANT: Bypass mode is for use with an external regulator as the supply
voltage only. Never place the regulator in bypass mode when the V
voltage is greater than the specifications given in Table 9.1 on page 47. Doing so
may cause permanent damage to the device.
