Bits 5 and 4—Instruction Fetch/Data Access Select A (IDA1, IDA0): These bits specify whether
an instruction fetch cycle or data access cycle is to be selected as the bus cycle used as a channel A
break condition.
Bit 5:
IDA1
Bit 4:
IDA0
Description
0
0
Channel A user break interrupt is not generated
(Initial value)
1
Instruction fetch cycle is selected as break condition
1
0
Data access cycle is selected as break condition
1
Instruction fetch cycle or data access cycle is selected as break condition
Bits 3 and 2—Read/Write Select A (RWA1, RWA0): These bits specify whether a read cycle or
write cycle is to be selected as the bus cycle used as a channel A break condition.
Bit 3:
RWA1
Bit 2:
RWA0
Description
0
0
Channel A user break interrupt is not generated
(Initial value)
1
Read cycle is selected as break condition
1
0
Write cycle is selected as break condition
1
Read cycle or write cycle is selected as break condition
Bits 1 and 0—Operand Size Select A (SZA1, SZA0): These bits select the operand size of the bus
cycle used as a channel A break condition.
Bit 1:
SZA1
Bit 0:
SZA0
Description
0
0
Operand size is not included in break conditions
(Initial value)
1
Byte access is selected as break condition
1
0
Word access is selected as break condition
1
Longword access is selected as break condition
Notes: When a break is to be executed on an instruction fetch, clear the SZA0 bit to 0. All
instructions are regarded as being accessed using word size (instruction fetches are always
performed as longword).
In the case of an instruction, the operand size is word; in the case of a CPU/DMAC, E-
DMAC data access, it is determined by the specified operand size. Note that the operand
size is not determined by the bus width of the space accessed.
