Description

Multi-function Timer Pulse Unit 3

(MTU3a)

[RZ/G2UL (Type-1)]

● 9 channels (16 bits × 8 channels, 32 bits × 1 channel)

[RZ/G2UL (Type-2)]

● 8 channels (16 bits × 7 channels, 32 bits × 1 channel)

[RZ/G2UL (Type-1) RZ/G2UL (Type-2)]

● Module clock frequency (P0ϕ): 100 MHz

● Maximum 28 lines of pulse inputs/outputs and 3 lines of pulse inputs

● 14 types of count clocks selectable

● Input capture function

● 39 outputs compare and input capture registers

● Counter clear operation (Simultaneous counter clearing by Compare match or Input capture is

available)

● Simultaneous writing to multiple timer counters (TCNT)

● Synchronous input/output of each register due to synchronous operation of the counter

● Buffered operation

● Cascade-connected operation

● 43 types of interrupt sources

● Automatic transfer of register data

● Pulse output modes

Toggle, PWM, complementary PWM, and reset-synchronized PWM modes

● Synchronization of multiple counters

● Phase counting mode

– 16-bit mode (channel 1 and 2)

– 32-bit mode (channel 1 and 2)

● Counter function of dead time compensation

● Digital filter functions for the input capture and external count clock pin

Port Output Enable 3

(POE3)

[RZ/G2UL (Type-1) RZ/G2UL (Type-2)]

● Control of the high-impedance state of the MTU3a waveform output pins

● Activation with four input pins

● Activation on detection of short-circuited outputs

● Activation by register write

● Additional programming of output control target pins is possible.

Watchdog Timer

(WDT)

[RZ/G2UL (Type-1) RZ/G2UL (Type-2)]

● 2 channels

● A counter overflow can reset the LSI

● CPU parity error can reset the LSI

General Timer

(GTM)

[RZ/G2UL (Type-1) RZ/G2UL (Type-2)]

● 32 bits × 3 channels

● Two operating modes
