Table 71. Register 0xDC—BREAKPOINTS (Block W)

Byte

Bit Name

R/W

Description

Data length

Block W

The length of breakpoints data to write. Maximum = 64 bytes.

[128:1]

Data

Block W

Bit 0 of Byte 1 sets the breakpoint for State 1, Bit 1 of Byte 1 sets the breakpoint for State 2,

incrementing up to Bit 7 of Byte 64 sets the breakpoint for State 1024. Maximum value of N = 128.

Table 75. Black Box Data Format

Byte

Field

Description

[1:0]

Each black box record has a unique ID but that ID is the same for all black box records across multiple

devices.

Empty

0 = used, 1 = empty.

Reserved

Reserved.

Page

Page index that current record is saved in.

JUMP_TYPE

The jump (transition from one state to another) was due to sequence action, receipt of jump message.

ACTION_INDEX
