Page 89: Data Section Defining Directives（.Rodata, .Data
Example: .section .data Defines a .data section.  Note  The data space allocated by the data-define directive is as follows: 1 byte: .byte 2 bytes: .short, .hword, .word, .int 4 bytes: .long S5U1C17001C Manual Seiko Epson Corporation (Rev. 1.0)
Page 90: Bss Section Defining Directive （.Bss
.align VAR2: .skip Defines the 4-byte global variable VAR2. • Areas in .bss sections can be secured using the .skip directive. The .space directive cannot be used because it has an initial data. S5U1C17001C Manual Seiko Epson Corporation (Rev. 1.0)
Page 91: Data Defining Directives （.Long, .Short, .Byte, .Ascii, .Space
If <1-byte data> is omitted, the area is filled with 0x0. To fill the area with 0x0, the .zero directive (see the next page) can also be used. Example: .space 4,0xff Sets 0xff to the 4-byte area beginning from the current address. .zero （= .space 4,0x0） S5U1C17001C Manual Seiko Epson Corporation (Rev. 1.0)
Page 92: Area Securing Directive （.Zero
This directive secures a <length> bytes of blank area in the current .bss section. The area begins from the current address unless it is immediately preceded by the .align directive. .section .bss Example: .global VAR1 .align VAR1: .zero Secures an space for the 4-byte global variable VAR1. S5U1C17001C Manual Seiko Epson Corporation (Rev. 1.0)
Page 93: Alignment Directive （.Align
The .align directive is valid for only the immediately following data definition or area securing directive. Therefore, when defining data that requires alignment, you need to use the .align directive for each data definition directive. S5U1C17001C Manual Seiko Epson Corporation 6-10 (Rev.
Page 94: Global Declaring Directive （.Global
Makes global declaration of a symbol. The declaration made in a file with a symbol defined converts that symbol to a global symbol which can be referred to from other modules. Example:.global SUB1  Note  The symbols are always defined as a local symbol unless it is declared using this directive. S5U1C17001C Manual Seiko Epson Corporation 6-11 (Rev. 1.0)

Run ptd as follows at the command prompt. Example: C:\EPSON\GNU17V3\>ptd s1c17554.psa –e 0x27ffc=0xff80,0xffff This command rewrites the value at address 0x27ffc to 0xff80 and the value at address 0x27ffe to 0xffff inside s1c17554.psa and outputs to s1c17554_ptd.psa. The addresses for Flash Protection Bits in S1C17754 are 0x27ffc (write-protect) and 0x27ffe (data-read-protect).
