Specification

Multi-function timer

pulse unit 2 (MTU2)

• Maximum 16 lines of pulse input/output and 3 lines of pulse input

based on six channels of 16-bit timers

• 21 output compare and input capture registers

• Input capture function

• Pulse output modes

Toggle, PWM, and complementary PWM

• Synchronization of multiple counters

• Complementary PWM output mode

 Non-overlapping waveforms output for 3-phase inverter control

 Automatic dead time setting

 0% to 100% PWM duty value specifiable

 A/D conversion delaying function

 Interrupt skipping at crest or trough

• Reset-synchronized PWM mode

Three-phase PWM waveforms in positive and negative phases can be

output with a required duty value

• Phase counting mode

Two-phase encoder pulse counting available

Multi-function timer

pulse unit 2S (MTU2S)

• Subset of MTU2, included in channels 3 to 5

• Operating at 100 MHz max.

Port output enable 2

(POE2)

• High-impedance control of high-current pins at a falling edge or low-

level input on the

POE pin

Compare match timer

(CMT)

• Two-channel 16-bit counters

• Four types of clock can be selected (Pφ/8, Pφ/32, Pφ/128, and Pφ/512)

• DMA transfer request or interrupt request can be issued when a

compare match occurs

Serial communication

interface (SCI)

• Four channels (SH7285 and SH7286)

Two channels (SH7243)

• Clocked synchronous or asynchronous mode selectable

• Simultaneous transmission and reception (full-duplex communication)

supported

• Dedicated baud rate generator
