Overview
Features
Features
HCS12X Core
- 16-bit HCS12X CPU
- Upward compatible with HCS12 instruction set
- Interrupt stacking and programmer's model identical to HCS12
- Instruction queue
- Enhanced indexed addressing
- Enhanced instruction set
- EBI (external bus interface)
- MMC (module mapping control)
- INT (interrupt controller)
- DBG (debug module to monitor HCS12X CPU and XGATE bus activity)
- BDM (background debug mode)
XGATE
- Peripheral co-processor
- Parallel processing module offloads the CPU by providing high-speed data processing transfer between peripheral modules, RAM and I/O ports
- Data transfer between flash EEPROM, peripheral modules and I/O ports
PIT (periodic interrupt timer)
- Four timers with independent time-out periods
- Time-out periods selectable between 1 and 224 bus clock cycles
CRG
- Low noise/low power Pierce oscillator
- Phase-lock look (PLL)
- COP watchdog
- Real-time interrupt
- Clock monitor
- Fast wake-up from stop mode
