Peripherals
An interrupt request can be sent to the CPU on
completion of the specified number of transfers
Various DMAC transfer requests are provided:
– External request
– On-chip peripheral modules (Transfer requests from the
SCI, SCF, and TMU can be accepted on all channels.)
– Auto-request (A transfer request is generated
automatically within the DMAC)
Channel functions: different transfer modes
can be set for each channel
I Data Transfer Controller (DTC)
Transfer possible over any number of channels
3 transfer modes: normal, repeat, and block transfer
One activation source can trigger a number of data
transfers (chain transfer)
Direct specification of 32-bit address space
Activation by software allowed
Transfer can be set in byte, word, or longword units
I Host Interface (HIF)
Connectable to the main CPU with parallel bus
HIF boot function eliminates the need for boot ROM
I Motor Management Timer (MMT)
Triangular-wave comparison-type 6-phase PWM
waveform output with non-overlap dead times
Non-overlap times generated by timer’s dead time
counters decrease torque pulsations/harmonics for
improved voltage utilization
Toggle output synchronized with PWM period
PWM output halted by external signal
PWM duty programmable between 0 and 100%
Output-off functions
Adjustable carrier frequency for low switching losses
and less audible noise
I Multi-function Timer Unit (MTU)
Up to 12-phase PWM output with synchronous
operation
2-phase encoder pulse up/down count
Counter cascade mode to 32-bit counter
High sink current (15mA) for 6 pins; can directly
drive opto-isolators
A/D converter trigger signal can be generated
Dead time can be generated automatically
I Analog Interfaces
4- to 32-channel 10-bit successive-approximation
A/D converter
– Precise current detection for current control
– Three sample-and-holds with maximum conversion time
of 5.4 microseconds
2 channel 8-bit D/A converter
