High performance
Low power dissipation
Improved code efficiency and operating performance have been realized through the use of two ISA
(Instruction Set Architecture) modes - 16- and 32-bit ISA modes.

The 16-bit ISA mode instructions are compatible with the /+25
code efficiency at the object level.
The 32-bit ISA mode instructions are compatible with the TX39 instructions of superior operating
performance at the object level.
Almost all instructions can be executed with one clock.
High performance is possible via a three-operand operation instruction.
5-stage pipeline
Built-in high-speed memory
DSP function: A 32-bit multiplication and accumulation operation can be executed with one clock.
Optimized design using a low power dissipation library
Standby function that stops the operation of the processor core
Independency of the entry address
Automatic generation of factor-specific vector addresses
Automatic update of interrupt mask levels
ROM correction function: 1 word K 8 blocks, 8 words K 4 blocks
Expandable to 16 megabytes (for both programs and data)
External data bus:
Separate bus/multiplexed bus
Chip select/wait controller
Activated by an interrupt or software
Data to be transferred to internal memory, internal I/O, external memory, and external I/O
16-bit interval timer mode
16-bit event counter mode
16-bit PPG output (every 4 channels, synchronous outputs are possible)
Input capture function
2-phase pulse input counter function (4 channels assigned to perform this function): Multiplication-
by-4 mode
