Watch Timer
Directly operates with the oscillation clock
Read/Write accessible Second/Minute/Hour registers
Signals interrupts
16-bit
I/O Timer
(2 channels)
Signals an interrupt when overflowing
Supports Timer Clear when a match with Output Compare (Channel 0)
Operation clock freq. : fsys, fsys/21, fsys/22, fsys/23, fsys/24, fsys/25, fsys/26, fsys/27
(fsys
= System clock freq.)
I/O Timer 0 (clock input FRCK0) corresponds to ICU 0/1, OCU 0/1/2/3
I/O Timer 1 (clock input FRCK1) corresponds to ICU 2/3/4/5, OCU 4/5/6/7
16-bit
Output Compare
(8 channels)
Signals an interrupt when a match with 16-bit I/O Timer
Eight 16-bit compare registers.
A pair of compare registers can be used to generate an output signal.
OCU 6/7 outputs are shared with ICU 3/5 inputs
16-bit
Input Capture
(6 channels)
Rising edge, falling edge or rising & falling edge sensitive
Six 16-bit Capture registers
Signals an interrupt upon external event
ICU 3/5 inputs are shared with OCU 6/7 outputs
8/16-bit
Programmable Pulse
Generator
(6 channels)
Supports 8-bit and 16-bit operation modes
Twelve 8-bit reload counters
Twelve 8-bit reload registers for L pulse width
Twelve 8-bit reload registers for H pulse width
A pair of 8-bit reload counters can be configured as one 16-bit reload counter or as
8-bit prescaler plus 8-bit reload counter
Operation clock freq. : fsys, fsys/21, fsys/22, fsys/23, fsys/24 or 102.4
s at fosc = 5 MHz
(fsys
= System clock frequency, fosc = Oscillation clock frequency)
CAN Interface
(up to 5 channels)
2 channels
5 channels
Conforms to CAN Specification Version 2.0 Part A and B
Automatic re-transmission in case of error
Automatic transmission responding to Remote Frame
Prioritized 16 message buffers for data and ID’s
Supports multiple messages
Flexible configuration of acceptance filtering :
Full-bit compare/Full-bit mask/Two partial bit masks
Supports up to 1 Mbps
MB90F394H, MB90F395H, MB90V390H, MB90V390HA :
Do not use CAN message buffer RAM and clock modulator at the same time.
Stepping Motor
Controller
(6 channels)
Four high current outputs with controlled slew rate for each channel
Synchronized two 8-bit PWM’s for each channel
External Interrupt
(8 channels)
Can be programmed edge sensitive or level sensitive
Sound Generator
8-bit PWM signal is mixed with tone frequency from 8-bit reload counter
PWM frequency : 62.5 kHz, 31.2 kHz, 15.6 kHz, 7.8 kHz at System clock
= 16 MHz
Tone frequency : PWM frequency/2/ (reload value
+ 1)
