Note:
1. All Power Reduction Registers set. Typical numbers measured at T = 25°C if nothing else is specified.
2. All parameters measured as the difference in current consumption between module enabled and disabled. All data at
V_CC = 3.0V, Clk_SYS = 1 MHz External clock with no prescaling, T = 25°C.
