USER’S MANUAL
3.1.4 Masked ROM Module (MRM) — (MC68HC16Z2/Z3 Only)
• 8-Kbyte array, accessible as bytes or words
• User-selectable default base address
• User-selectable bootstrap ROM function
• User-selectable ROM verification code
3.1.5 Analog-to-Digital Converter (ADC)

• One 8-bit dual function port
3.1.7 Multichannel Communication Interface (MCCI) — (MC68HC16Z4/CKZ4 Only)
• Two channels of enhanced SCI (UART)
• One channel of SPI
3.1.8 General-Purpose Timer (GPT)
• Two 16-bit free-running counters with prescaler
• Three input capture channels
• Four output compare channels
• One input capture/output compare channel
• One pulse accumulator/event counter input
• Two pulse width modulation outputs
• Optional external clock input
3.2 Intermodule Bus
The intermodule bus (IMB) is a standardized bus developed to facilitate the design of
modular microcontrollers. It contains circuitry that supports exception processing, ad-
dress space partitioning, multiple interrupt levels, and vectored interrupts. The stan-
dardized modules in M68HC16 Z-series MCUs communicate with one another via the
IMB. Although the full IMB supports 24 address and 16 data lines, M68HC16 Z-series
MCUs use only 20 address lines. ADDR[23:20] follow the state of ADDR19.
3.3 System Block Diagram and Pin Assignment Diagrams
Figure 3-1 is a functional diagram of the MC68HC16Z1/CKZ1/CMZ1 MCU. Refer to
Figure 3-2 for a functional diagram of the MC68HC16Z2/Z3 MCU. Figure 3-3 is a
functional diagram of the MC68HC16Z4/CKZ4 MCU. Although diagram blocks repre-
sent the relative size of the physical modules, there is not a one-to-one correspon-
dence between location and size of blocks in the diagram and location and size of
integrated-circuit modules.
