Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2) with selectable input capture,
output compare, and PWM capability on each channel
8-channel, 8-bit successive approximation analog-to-digital converter (ADC)
BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging
Internal pullups on IRQ and RST to reduce customer system cost
Clock generator module with on-chip 32-kHz crystal compatible PLL (phase-lock loop)
Up to 33 general-purpose input/output (I/O) pins, including:
–
–
Selectable pullups on inputs only on ports A, C, and D. Selection is on an individual port bit basis.
During output mode, pullups are disengaged.
High current 10-mA sink/10-mA source capability on all port pins
Higher current 15-mA sink/source capability on PTC0–PTC4
Timebase module with clock prescaler circuitry for eight user selectable periodic real-time
interrupts with optional active clock source during stop mode for periodic wakeup from stop using
an external 32-kHz crystal
Oscillator stop mode enable bit (OSCSTOPENB) in the CONFIG register to allow user selection of
having the oscillator enabled or disabled during stop mode
8-bit keyboard wakeup port
40-pin plastic dual-in-line package (PDIP), 42-pin shrink dual-in-line package (SDIP), or 44-pin
quad flat pack (QFP)
Specific features of the MC68HC908GP32 in 40-pin PDIP are:

Enhanced HC05 programming model
Extensive loop control functions
16 addressing modes (eight more than the HC05)
16-bit index register and stack pointer
Memory-to-memory data transfers
Fast 8 × 8 multiply instruction
Fast 16/8 divide instruction
Binary-coded decimal (BCD) instructions
Optimization for controller applications
Efficient C language support
26 shared-function I/O pins
Five or seven dedicated I/O pins, depending on package choice
Port C is only 5 bits: PTC0–PTC4
Port D is only 6 bits: PTD0–PTD5; single 2-channel TIM module
Port C is only 5 bits: PTC0–PTC4
Port D is 8 bits: PTD0–PTD7; dual 2-channel TIM modules
Port C is 7 bits: PTC0–PTC6
Port D is 8 bits: PTD0–PTD7; dual 2-channel TIM modules
