• (For 32 bits)
Monitor and write only b8 to b11 and b28 to 31 of the buffer memory.
Example:
The monitor value is 00070003H when monitoring BM0=87654321H 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 0004H when monitoring BM0=4321H as mask type 4.
BM0=1000H when writing input value 4321H to BM0=0000H 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 00080004H when monitoring BM0=87654321H as mask type 4.
BM0=50001000H for writing input value 87654321H to BM0=00000000H as mask type 4.
