Devices in the MC9S08RD/RE/RG Series
Table 1-1 lists the devices available in the MC9S08RD/RE/RG series and summarizes the differences in
functions and configuration among them.
Timer/Pulse-Width
Modulator (TPM1)
2-channel, 16-bit timer/pulse-width modulator (TPM1) module that can operate as a
free-running counter, a modulo counter, or an up-/down-counter when the TPM is
configured for center-aligned PWM
Selectable input capture, output compare, and edge-aligned or center-aligned PWM
capability on each channel
Keyboard Interrupt Ports
(KBI1, KBI2)
Providing 12 keyboard interrupts
Eight with falling-edge/low-level plus four with selectable polarity
KBI1 inputs can be configured for edge-only sensitivity or edge-and-level sensitivity
Carrier Modulator Timer
(CMT)
Dedicated infrared output (IRO) pin
Drives IRO pin for remote control communications
Can be disconnected from IRO pin and used as output compare timer
IRO output pin has high-current sink capability
Development Support
Background debugging system (see also the Development Support chapter)
Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus
two more breakpoints in on-chip debug module)
Debug module containing two comparators and nine trigger modes. Eight deep FIFO
for storing change-of-flow addresses and event-only data. Debug module supports
both tag and force breakpoints.
Port Pins
Eight high-current pins (limited by maximum package dissipation)
Software selectable pullups on ports when used as input. Selection is on an individual
port bit basis. During output mode, pullups are disengaged.
39 general-purpose input/output (I/O) pins, depending on package selection
Package Options
28-pin plastic dual in-line package (PDIP)
28-pin small outline integrated circuit (SOIC)
32-pin low-profile quad flat package (LQFP)
44-pin low-profile quad flat package (LQFP)
48-pin quad flat package (QFN)
System Protection
Optional computer operating properly (COP) reset
Low-voltage detection with reset or interrupt
Illegal opcode detection with reset
Illegal address detection with reset (some devices don’t have illegal addresses)
