General Release Specification
Low-Power Modes
consumption. Wait current specifications assume CPU operation only
and do not include current consumption by any other subsystems.
During wait mode, the I bit in the CCR is cleared to enable interrupts. All
other registers, memory, and input/output lines remain in their previous
states. The timer may be enabled to allow a periodic exit from wait mode.
6.6 Low-Power Reset
Low-power reset mode is entered when a logic 0 is detected on the
LPRST pin. When in this mode (as long as LPRST is held low), the MCU
is held in reset and all internal clocks are halted. Applying a logic 1 to
LPRST will cause the part to exit low-power reset mode and begin
counting out the 4064-cycle oscillator stabilization period. Once this time
has elapsed, the MCU will begin operation from the reset vectors
($3FFE–$3FFF).
