2. DEVICE RANGE THAT CAN BE SET
• (For 32 bits)
Monitor and write only b8 to b11 and b28 to 31 of
the buffer memory.
Example:
The monitor value is 00070003
H when monitoring
BM0=87654321
H as mask type 3.
BM0=05000100H when writing input value
87654321H to BM0=00000000H as mask type 3.
(e) Mask type 4
• (For 16 bits)
Monitor and write only b12 to b15 of the buffer
memory.
Example:
The monitor value is 0004
H when monitoring
BM0=4321
H as mask type 4.
BM0=1000H when writing input value 4321H to
BM0=0000
H as mask type 4.
• (For 32 bits)
Monitor and write only b12 to b15 and b28 to 31
of the buffer memory.
Example:
The monitor value is 00080004
H when monitoring
BM0=87654321H as mask type 4.
BM0=50001000
H for writing input value
87654321
H to BM0=00000000H as mask type 4.
(f) Mask type 5
•(For 16 bits)
Monitor and write only b0 to b7 of the buffer
memory.
Example:
The monitor value is 0021
H when monitoring
BM0=4321H as mask type 5.
BM0=0021
H when writing input value 4321H to
BM0=0000H as mask type 5.
•(For 32 bits)
Monitor and write only b0 to b7 and b16 to 23 of
the buffer memory.
Example:
The monitor value is 00650021H when monitoring
BM0=87654321
H as mask type 5.
BM0=00650021
H when writing input value
87654321H to BM0=00000000H as mask type 5.
(g) Mask type 6
•(For 16 bits)
Monitor and write only b8 to b15 of the buffer
memory.
Example:
The monitor value is 0043
H when monitoring
BM0=4321
H as mask type 6.
BM0=2100
H when writing input value 4321H to
BM0=0000
H as mask type 6.
