The Ignore the Low Byte function of the ZDI Address Match
1 registers is disabled. If BRK_ADDR1 is set to 1, ZDI
initiates a BREAK when the entire 24-bit address,
ADDR[23:0], matches the 3-byte value {ZDI_ADDR1_U,
ZDI_ADDR1_H, ZDI_ADDR1_L}.
The Ignore the Low Byte function of the ZDI Address Match
1 registers is enabled. If BRK_ADDR1 is set to 1, ZDI
initiates a BREAK when only the upper 2 bytes of the 24-bit
address, ADDR[23:8], match the 2-byte value
{ZDI_ADDR1_U, ZDI_ADDR1_H}. As a result, a BREAK
can occur anywhere within a 256-byte page.
The Ignore the Low Byte function of the ZDI Address Match
1 registers is disabled. If BRK_ADDR0 is set to 1, ZDI
initiates a BREAK when the entire 24-bit address,
ADDR[23:0], matches the 3-byte value {ZDI_ADDR0_U,
ZDI_ADDR0_H, ZDI_ADDR0_L}.
The Ignore the Low Byte function of the ZDI Address Match
1 registers is enabled. If the BRK_ADDR1 is set to 0, ZDI
initiates a BREAK when only the upper 2 bytes of the 24-bit
address, ADDR[23:8], match the 2 bytes value
{ZDI_ADDR0_U, ZDI_ADDR0_H}. As a result, a BREAK
can occur anywhere within a 256-byte page.
ZDI SINGLE STEP mode is disabled.
ZDI SINGLE STEP mode is enabled. ZDI asserts a BREAK
following execution of each instruction.
