420 cycle loop: 384 DBNE cycles plus subroutine entry to stimulate stacking (RAM access)
Configured to loop-back mode using a bit rate of 1Mbit/s
Configured to master mode, continuously transmit data (0x55 or 0xAA) at 4Mbit/s
Configured into loop mode, continuously transmit data (0x55) at speed of 57600 baud
Configured to toggle its pins at the rate of 40kHz
The peripheral shall be configured in output compare mode. Pulse accumulator and modulus
counter enabled.
The peripheral is configured to operate at its maximum specified
frequency and to continuously convert voltages on all input channels in sequence.
VREG supplying 1.8V from a 5V input voltage, PLL on
A.1.10.3 Stop Current Conditions
Unbonded ports must be correctly initialized to prevent current consumption due to floating inputs. Typical
Stop current is measured with V_DD35=5V, maximum Stop current is measured with V_DD35=5.5V. Pseudo
Stop currents are measured with the oscillator configured for 4MHz LCP mode. Production test parameters
are tested with a 4MHz square wave oscillator.
