RD - Register Display

3-191

Note the following when specifying any arguments in the

command line:

❏ The +, -, or = qualifier applies to the next register range only.

❏ If no qualifier is specified, a + is assumed, even for the

default.

❏ All device names should appear before any register names.

❏ The command line arguments are parsed from left to right,

with each argument being processed after parsing; thus the

sequence in which qualifiers and registers are organized has

an impact on the resultant register mask.

❏ When specifying a register range, REG1 and REG2 do not

have to be of the same class.

❏ The register mask used by RD is also used by all exception

handler routines, including the trace and breakpoint

exception handlers.

The MPU registers, in ordering sequence, are (total of 117 registers):

= The device or register range is to be set. This character

followed by DEF in the DNAME argument restores the

/ A required delimiter between device names and register

ranges
