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.
Table A-10. shows the configuration of the peripherals for typical run current.

Peripheral
Configuration
S12XCPU
420 cycle loop: 384 DBNE cycles plus subroutine entry to stimulate stacking (RAM access)
XGATE
XGATE fetches code from RAM, XGATE runs in an infinite loop, reading the Status and Flag
registers of CAN’s, SPI’s, SCI’s in sequence and doing some bit manipulation on the data
MSCAN
Configured to loop-back mode using a bit rate of 500kbit/s
SPI
Configured to master mode, continuously transmit data (0x55 or 0xAA) at 2Mbit/s
SCI
Configured into loop mode, continuously transmit data (0x55) at speed of 19200 baud
IIC
Operate in master mode and continuously transmit data (0x55 or 0xAA) at 100Kbit/s
PWM
Configured to toggle its pins at the rate of 1kHz
ECT
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.
PIT
PIT is enabled, Micro-timer register 0 and 1 loaded with $0F and timer registers 0 to 3 are loaded
with $03/07/0F/1F.
RTI
Enabled with RTI Control Register (RTICTL) set to $59
Overhead
VREG supplying 1.8V from a 5V input voltage, core clock tree active, PLL on
