Displays a description of the registers available for the current target.
REGINFO [{, qualifier}]
[=address-range] [{;windowid |
;fileid}]
where:
allDisplays information for all register types (target, user,
and access).
targetDisplays information for the registers on the connected target.
userDisplays information for the memory mapped registers defined in one or more BCD files attached to the target connection, if any.
accessDisplays information for the target access registers.
detailsDisplays
additional information for each register. The information displayed depends
on the specified register type (target, user,
or access).
bitfieldsDisplays
information for any bit fields associated with the specified register
type (target, user, or access).
match:[@]register_nameDisplays information for all registers with names
that contain the given string. The string can form any part of the
name. For example, match:SPSR matches all register
names beginning with SPSR.
address-rangeDisplays information for any memory mapped registers within the specified address range.
,windowid | ,fileidIdentifies the window or file where the command is to send the output.
If you do not supply a , or windowid, parameter,
or there is no window or file associated with the ID, the output
is displayed on the screen. If you are using the GUI, then the output
is displayed in the Output view.fileid
The REGINFO command enables you to view the list of available registers for the current connection. You can list:
All registers.
Registers only for the connected target.
User-defined memory mapped register and peripheral registers defined in any BCD files associated with the current connection.
Target access registers.
By default, a summary of the registers is displayed. However, you can choose to display:
More detailed information for each register, such as:
the size (in bytes)
type of value (such as, signed char and unsigned
long)
type of register: core register, memory-mapped
register, target access register.
The bitfields for any registers that have them (such as the CPSR register).
The following examples show how to use REGINFO:
reginfo,match:@SPSRLists all the SPSR registers:
Register @SPSR_FIQ (display name "SPSR") Register @SPSR_SVC (display name "SPSR") Register @SPSR_ABT (display name "SPSR") Register @SPSR_IRQ (display name "SPSR") Register @SPSR_UND (display name "SPSR")
reginfo,match:SPSR_SVC,bitfieldsDisplays the following bit field information for the SPSR_SVC register:
Register @SPSR_SVC (display name "SPSR")
bit-fields:
