System Protection
• 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
• 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
• 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
• 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.
• 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
• 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)
• 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)
