Table 44: Flash Lock Protection Bits Definition
11.4 Debug Commands
The debug commands are shown in Table 45.
Some of the debug commands are described
in further detail in the following sections
CC1110Fx/CC1111Fx supports up to four hardware
breakpoints. When a hardware breakpoint is
enabled it will compare the CPU address bus
with the breakpoint. When a match occurs, the
CPU is halted.
11.4.1
Debug Configuration
commands WR_CONFIG
When issuing the SET_HW_BRKPNT debug
command, the external host must supply three
data bytes that define the hardware
breakpoint. The hardware breakpoint itself
consists of 18 bits while three bits are used for
control purposes. The format of the three data
bytes for the SET_HW_BRKPNT command is
as follows.
The
and
RD_CONFIG are used to access the debug
configuration data byte. The format and
description of this configuration data is shown
in Table 46
11.4.2
Debug Status
The first data byte consists of the following:
A debug status byte is read using the
READ_STATUS command. The format and
description of this debug status is shown in
Table 47.
Bit Description
7:5 Unused
The READ_STATUS command is used e.g.
for polling the status of flash chip erase after a
CHIP_ERASE command or oscillator stable
status required for debug commands HALT,
RESUME, DEBUG_INSTR, STEP_REPLACE,
and STEP_INSTR.

the hardware breakpoint while the third data
byte consists of bits 7 - 0 of the hardware
