Regulator Mode Selection
REG0 offers a low power mode intended for use when the device is in suspend mode. In this low power mode, the
REG0 output remains as specified; however the REG0 dynamic performance (response time) is degraded. See
Table 8.1 for normal and low power mode supply current specifications. The REG0 mode selection is controlled via
the REGMOD bit in register REG0CN.
