29. User Break Controller (UBC)
29.2.7 Execution Count Break Register 1 (CETR1)
CETR1 is a readable/writable 32-bit register which specifies the number of the channel hits before
a break occurs. A maximum value of 2¹² – 1 can be specified. When the execution count value is
included in the match conditions by using the match condition setting register, the value of this
register is decremented by one every time the channel is hit. When the channel is hit after the
register value reaches H'001, a break occurs.
