8 Debugger
Notes
 Writing in units of 16 bits or 32 bits is performed in little endian format.
 The data write memory section is aligned to boundary addresses according to the size of data.
(gdb) c17 fw 0x3 0x9 0x0
For example, when a write memory section is specified as shown above, and because start address 0x3 and end address 0x9
are not located on 32-bit data boundaries, both are aligned to boundary addresses by setting the 2 low-order bits to 00 (LSB
= 0 for 16 bits). The following shows the actually executed command, where 32-bit data addresses 0x0 to 0x8 (byte data
addresses 0x0 to 0xb) are rewritten with data 0x00000000.
(gdb) c17 fw 0x0 0x8 0x0
 If the specified address exceeds the 24-bit range, an error is assumed.
 Data parameters are only effective for the 8 low-order bits for c17 fb, 16 low-order bits for c17 fh, and 32 low-order bits
for c17 fw, with excessive bits being ignored. For example, when data 0x100 is specified in c17 fb, it is processed as
0x00.
 If the end address is smaller than the start address, an error is assumed.
