21.1 Device-specific information

21.1.1 VREGEN

There is no VREGEN pin implemented on this device.

21.1.2 Modes of Operation

21.1.2.1 Run Mode

VREG enters run mode whenever the CPU is neither in Stop nor in Pseudo Stop mode. Both regulating

loops operate in Run mode with full performance.

21.1.2.2 Standby Mode

VREG enters Standby mode when the CPU operates either in Stop or in Pseudo Stop mode. The supply of

the core logic as well as the oscillators are derived from two voltage clamps. Standby mode minimizes

quiescent current drawn by the voltage regulator block.

21.1.2.3 Shutdown Mode

VREG Shutdown mode is not available on MC9S12H family devices.
