condition setting registers (CBR0 and CBR1). (Sequential break involves two cases such that
channel 0 break condition is satisfied then channel 1 break condition is satisfied, and vice
versa.) To use the sequential break function, clear the MFE bit of the match condition setting
register and the BIE bit of the match operation setting register of the first channel in the
sequence, and set the MFE bit and specify the number of the second channel in the sequence
using the MFI bit in the match condition setting register of the second channel in the sequence.
If the sequential break condition is set, the condition match flag is set every time the match
condition is satisfied for each channel. When the condition has been satisfied for the first
channel in the sequence but not for the second channel in the sequence, clear the condition
match flag for the first channel in the sequence in order to release the first channel in the
sequence from the match state.
