(f) Mask type 5
• (For 16 bits)
Monitor and write only b0 to b7 of the buffer memory.
Example:
The monitor value is 0021H when monitoring BM0=4321H as mask type 5.
BM0=0021H 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=87654321H as mask type 5.
BM0=00650021H 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 0043H when monitoring BM0=4321H as mask type 6.
BM0=2100H when writing input value 4321H to BM0=0000H as mask type 6.
