Serial IO
transfer can be started from MSB or LSB
supports internal clock synchronized
transfer and external clock synchronized
transfer
prescaler for shift clock allows:
fRES/3, fRES/4, fRES/5, fRES/6, fRES/7,
fRES/8
Clock disable
supports positive and negative clock
edge synchronization
Sound Generator
(Buzzer)
8-bit PWM signal is mixed with tone fre-
quency from 8-bit reload counter
PWM clock by internal prescaler:
fRES/1, fRES/2, fRES/4, fRES/8
tone frequency: PWM frequency / 2 /
(reload value + 1)
Clock disable
Target frequency to be programma-
ble in the range of 300 Hz to 5 kHz
fRES/1 and a reload value of 5 result
in 5.2 kHz at fRES = 16MHz,
fRES/4 and a reload value of 25
result in 300.48 Hz @ fRES = 16MHz
Stepper Motor Control
(4 channels)
four high current outputs for each chan-
nel
two synchronized 8-bit PWMs per chan-
nel
internal prescaling for PMW clock:
fRES, fRES/2, fRES/4, RES/5, fRES/6, fres/8
includes zero detection circuit
Clock disable
target frequency: 16 kHz
MB91F361G includes EMC
improved output drivers (longer slew
rate)
UART
(3 channels)
U-Timer
(1 per UART)
serial I/O port for performing asynchro-
nous (start-stop synchronization) com-
munication
full duplex, double buffering
supports multi-processor mode
variable data length (7/8 bit)
1 or 2 stop bits
error detection function (parity, framing,
overrun)
interrupt function
NRZ type transfer format
baud rate generated by U-Timer
16-bit timer to generate the required
UART clock:
