Single-wire background debug interface. Same hardware Background Debug Mode (BDM) cable supports both
devices.
One version of CodeWarrior integrated development environment (IDE) and debugger supports both devices.
CodeWarrior stationary, project wizard, initialization wizard and Processor Expert make C-code migration
between devices easy.
SET/CLR registers on 16 pins (PTC and PTE).
Break point capability to allow single breakpoint setting
during in-circuit debugging, plus three more
breakpoints in on-chip debug module.
Integrated ColdFire DEBU interface with
single wire BDM connection supports the same
electrical interface used by the S08 family debug
modules.
On-chip in-circuit emulator (ICE) debug module
containing three comparators and nine trigger modes.
Eight deep FIFO for tracing change-of-flow addresses
and event-only data. Debug module supports both tag
and force breakpoints.
Classic ColdFire Debug B+ functionality mapped into
the single-pin BDM interface. 64 deep FIFO for tracing
processor status (PST) and debug data (DDATA). Real
time debug support, with 6 hardware breakpoints, four
PC, one address and one data, that can be configured
into a 1 or 2 level trigger with a programmable response.

ADC
– 24-Channel, 12-bit resolution, 2.5 µs conversion time, automatic compare function, 1.7 mV/°C
temperature sensor, internal bandgap reference channel, operation in stop3, and fully functional from 3.6 V to
1.8 V.
ACMPx
– Two analog comparators with selectable interrupt on rising, falling, or either edge of comparator output,
compare option to fixed internal bandgap reference voltage, and operation in stop3.
SCIx
– Two serial communications interface modules with optional 13-bit break.
SPIx
– Two serial peripheral interfaces with Full-duplex or single-wire bidirectional, double-buffered transmit and
receive, Master or Slave mode, MSB-first or LSB-first shifting.
IICx –
Two IICs with up to 100 kbps with maximum bus loading, multi-master operation, programmable slave
address, Interrupt driven byte-by-byte data transfer, supports broadcast mode and 10-bit addressing.
TPMx –
One 6-channel (TPM3) and two 3-channel (TPM1 and TPM2), selectable input capture, output compare,
or buffered edge- aligned or center-aligned PWM on each channel, and operation in stop3.
RTC –
(Real time counter) 8-bit modules counter with binary or decimal based prescaler; external clock source
for precise time base, time-of-day, calendar or task scheduling functions; Free running on-chip low power
oscillator (1 kHz) for periodical wake-up without external components; runs in all MCU modes
