Description
1
Pulse Width Modulation 1 – This signal provides a variable
pulse width output signal at a wide range of frequencies.
READI Message Data Out – Message data out (MDO2) is
an output signal used for uploading OTM, BTM, DTM, and
read/write accesses. External latching of MDO occurs on
the rising edge of MCKO. Eight MDO signals are
implemented.
Pulse Width Modulation 2 – This signal provides a variable
pulse width output signal at a wide range of frequencies.
PPMTX1 – Transmit data from PPM channel number 1.
Pulse Width Modulation 3 – This signal provides a variable
pulse width output signal at a wide range of frequencies.
PPMRX1 – Receive data to the PPM channel number 1.
Pulse Width Modulation 16 – This signal provides a
variable pulse width output at a wide range of frequencies.
Clock Input: MPWM16 can provide a clock input to
modulus clock submodule, MMCSM8
Pulse Width Modulation 17 – This signal provides variable
pulse width outputs at a wide range of frequencies.
Load Input: PWM17 can provide a load input to modulus
clock submodule, MMCSM8
READI Message Data Out – Message data out (MDO3) is
an output signal used for uploading OTM, BTM, DTM, and
read/write accesses. External latching of MDO occurs on
rising edge of MCKO. Eight MDO signals are implemented.
Pulse Width Modulation [18:19] – These signals provide
variable pulse width output signals at a wide range of
frequencies.
Clock and Load Input:
• MPWM18 can provide clock inputs to modulus counter
submodule MMCSM24
• MPWM19 can provide load inputs to modulus counter
submodule MMCSM24
READI Message Data Out – Message data out (MDO[6:7])
are output signals used for uploading OTM, BTM, DTM,
and read/write accesses. External latching of MDO occurs
on rising edge of MCKO. Eight MDO signals are
implemented.
