PWM Channel 0 Enable bit.
‘1’ – Enable the PWM Channel 0
‘0’ – Reset the PWM Channel 0. Only when the PWM channel is in reset state,
the stream of commands can be written into its data port, which in this case is
PWM_Command_Channel_0.
PWM Channel 1 Enable bit.
‘1’ – Enable the PWM Channel 1
‘0’ – Reset the PWM Channel 1. Only when the PWM channel is in reset state,
the stream of commands can be written into its data port, which in this case is
PWM_Command_Channel_1.
PWM Channel 2 Enable bit.
‘1’ – Enable the PWM Channel 2
‘0’ – Reset the PWM Channel 2. Only when the PWM channel is in reset state,
the stream of commands can be written into its data port, which in this case is
PWM_Command_Channel_2.
PWM Invalid Instruction Status bit for PWM Channel 0
‘0’ – No invalid command encountered during the instruction execution.
‘1’ – Invalid command encountered and this puts the PWM Channel 0 into reset
state.
PWM Invalid Instruction Status bit for PWM Channel 1
‘0’ – No invalid command encountered during the instruction execution.
‘1’ – Invalid command encountered and this puts the PWM Channel 1 into reset
state.
PWM Invalid Instruction Status bit for PWM Channel 2
‘0’ – No invalid command encountered during the instruction execution.
‘1’ – Invalid command encountered and this puts the PWM Channel 2 into reset
state.
External Trigger Enable
‘0’ – External triggering function is disabled
‘1’ – External triggering function is enabled
If enabled, GPIO-15 is used as trigger input/output
External Trigger Direction Selection
‘0’ – Active high external trigger input
‘1’ – Active low external trigger output
