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 occurs 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
occurs 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.
