Table A-9. shows the configuration of the peripherals for run current measurement.
Table A-9. Peripheral Configurations for Run Supply Current Measurements
Peripheral Configuration
MSCAN configured to loop-back mode using
a bit rate of 1Mbit/s
SPI configured to master mode,
continously transmit data (0x55 or
0xAA) at 1Mbit/s
SCI configured into loop mode,
continously transmit data (0x55) at
speed of 57600 baud
IIC operate in master mode and
continously transmit data (0x55 or
0xAA) at the bit rate of 100Kbit/s
PWM configured to toggle its pins at the
rate of 40kHz
ECT the peripheral shall be configured to
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.
XGATE XGATE fetches code from RAM,
XGATE runs in an infinite loop , it
reads the Status and Flag registers
of CAN’s, SPI’s, SCI’s in sequence
and does some bit manipulation on
the data
COP COP Warchdog Rate 2
24
RTI enabled, RTI Control Register
(RTICTL) set to $FF
API the module is configured to run from
the RC oscillator clock source.
PIT PIT isenabled,Micro-timer register0
and 1 loaded with $0F and timer
registers 0 to 3 are loaded with
$03/07/0F/1F.
DBG the module is enabled and the
comparators are configured to
trigger in outside range. The range
covers all the code executed by the
core.
