Specifications of MC68306FC16B

• Processor Type: M683xx 32-Bit
• Speed: 16MHz
• Voltage: 5V
• Mounting Type: Surface Mount
• Package / Case: 132-MQFP, 132-PQFP

• Features: -

The status register, illustrated in Figure 4-2, contains the interrupt mask (eight levels
available) and the following condition codes: overflow (V), zero (Z), negative (N), carry (C),
and extend (X). Additional status bits indicate that the processor is in the trace (T) mode
and/or in the supervisor (S) state.
4.3.1 Data Format Summary
The processor supports the basic data formats of the M68000 family. The instruction set
supports operations on other data formats such as memory addresses.
The operand data formats supported by the integer unit (IU) are the standard twos-
complement data formats defined in the M68000 family architecture. Registers, memory,
or instructions themselves can contain IU operands. The operand size for each instruction
is either explicitly encoded in the instruction or implicitly defined by the instruction
operation. Table 4-1 lists the data formats for the processor. Refer to M68000PM/AD,
M68000 Family Programmer’s Reference Manual, for details on data format organization
in registers and memory.
