Configuration
configured to loop-back mode using
a bit rate of 1Mbit/s
configured to master mode,
continously transmit data (0x55 or
0xAA) at 1Mbit/s
configured into loop mode,
continously transmit data (0x55) at
speed of 57600 baud
operate in master mode and
continously transmit data (0x55 or
0xAA) at the bit rate of 100Kbit/s
configured to toggle its pins at the
rate of 40kHz
the peripheral shall be configured to
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.
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 Warchdog Rate 2²⁴
enabled, RTI Control Register
(RTICTL) set to $FF
the module is configured to run from
the RC oscillator clock source.
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.
the module is enabled and the
comparators are configured to
trigger in outside range. The range
covers all the code executed by the
core.
