Electrical Characteristics
S12XS Family Reference Manual, Rev. 1.13
670 Freescale Semiconductor
4MHz loop controlled Pierce oscillator. Production test parameters are tested with a 4MHz square wave
oscillator.
Table A-10 shows the configuration of the peripherals for maximum run current
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.

Peripheral Configuration
S12XCPU 420 cycle loop: 384 DBNE cycles plus subroutine entry to stimulate stacking (RAM access)
MSCAN Configured to loop-back mode using a bit rate of 1Mbit/s
SPI Configured to master mode, continuously transmit data (0x55 or 0xAA) at 4Mbit/s
SCI Configured into loop mode, continuously transmit data (0x55) at speed of 57600 baud
PWM Configured to toggle its pins at the rate of 40kHz
TIM The peripheral shall be configured in output compare mode. Pulse accumulator and modulus
counter enabled.
ATD The peripheral is configured to operate at its maximum specified
frequency and to continuously convert voltages on all input channels in sequence.
Overhead VREG supplying 1.8V from a 5V input voltage, PLL on
Conditions are shown in Table A-9 at ambient temperature unless otherwise noted
