s3c89v 8 product overview 1 - 6 samsung confidentia l sam88rc overview the sam88rc instruction set is designed to support large register files. it features a full complement of 8 - bit arithmetic and logic operations, including multiply and divide. there are 78 instructions. no special i/o instructions are necessary because i/o control and data registers are mapped directly into the register file. decimal adjustment is included in binary - coded decimal (bcd) operations. 16 - bit word data can be incremented and decremented. flexible instructions for bit addressing, rotate, and shift operations complete the powerful data manipulation capabilities of the sam88rc instruction set. data types the sam88rc cpu performs operations on bits, bytes, bcd digits, and two - byte words. bits in the register file can be set, cleared, complemented, and tested. bits within a byte are numbere d from 7 to 0, where bit 0 is the least significant (right - most) bit. register addressing to access an individual register, an 8 - bit address in the range 0 - 255 or the 4 - bit address of a working register should be specified . paired registers can be used to construct 16 - bit data or 16 - bit program memory or data memory addresses. for detailed information about register addressing, please refer to section 2, "address spaces." addressing modes the re are seven addressing modes: register (r), indirect register (ir), indexed (x), direct (da), relative (ra), immediate (im), and indirect (ia). for detailed descriptions of these addressing modes, please refer to section 3, "addressing modes."
s3c89v 8 product overview 1 - 7 samsung confidentia l memory ove rview the s3c89v 8 has four kinds of memory space: ? internal program memory (rom) ? internal data memory (eeprom) ? internal data buffer (ram) ? internal register files (ram) a 16 - bit address bus and an 8 - bit data bus support prog ram memory and data memory operations. a separate 8 - bit address bus and the 8 - bit data bus carry addresses and data between the cpu and the register files. program memory (rom) the s3c89v 8 has an internal 47k - byte mask - programmable, read - onl y program memory (rom). the addresses 0eeh ? 0ffh of the rom are reserved as an interrupt vector area. data memory (eeprom) the s3c89v 8 has a 8 k - byte electrically erasable, programmable read - only memory (eeprom). a flexible and fast programming mode is provided to the user, and 1 to 32 bytes can be written at a time. the time is also programmable. the first page of eeprom (c000h - c01fh) is security area for unique serial number (read only) and the second page of eeprom (c020h - c03fh) is non erasable area for writing only (cannot be erased). an additional application program can be downloaded in the eeprom and it can be executed like program memory. internal data buffer (ram) the s3c8 9v 8 has a 1k - byte internal data buffer (extended data memory) as static ram. this memory can be used for i/o communication buffer or internal ram like internal registers. an external data memory instruction such as lde, lded, or ldei accesses these eeprom and ram. an additional application program can be downloaded in the ram and it can be executed like program memory.

s3c89v 8 product overview 1 - 9 samsung confidentia l 16 - bit timer the s3c89v 8 h as one 16 - bit timer. it consists of a timer control register(tcon), 16 - bit up counter(tch,tcl) and timer data(tdh,tdl). the clock source for the timer can be an external clock for contact mode or cpu clock for contactless mode depend on the cfg.4. the time r generates an interrupt whenever the tdh,tdl value are identical to tch,tcl respectively.
s3c89v 8 product overview 1 - 10 samsung confidentia l des (data encryption standard) s3c89v 8 has the hardware des which consists of key register block, data register block, des rounding block with s - box and p - box perm utation, and its control registers as figure 16 - 1. because each 64 - bit des key, k1 and k2 are write - only register, the key values are read - protected. on the other hand, to be encrypted or decrypted 64 - bit message should be loaded into 64 - bit desdata regis ters, from desdata0(msb) to desdata7(lsb). the desdata registers are read/write registers. des operation to execute single des, the control sequence is as follows: ? select bank1 by sb1 instruction ? loading a 64 - bit message into desdata0 (msb) to desdata 7 (lsb) registers ? writing des keys, k1 and/or k2: into key10 (msb) to key17 (lsb) registers for k1, key20 (msb) to key27 (lsb) for k2. ? select k1 or k2 by descon.5 ? select encryption or decryption by descon.0 ? start to des operation by descon.4 tripl e des operation encryption - decryption - encryption operation should be executed consecutively for encryption. there are two encryption steps with same key and one decryption step with the other key. if key1 is used for encryption key, then key 2 must be used for decryption key. on the other hand, to decrypt the data, decryption - encryption - decryption operation must be needed. in that case, k1 is for decryption and k2 is encryption key.
s3c89v 8 product overview 1 - 11 samsung confidentia l uart s3c89v 8 support 2 types of method for serial i/o during contact and /or contactless communication. those are ? sio falling edge interrupt ? uart tx/rx interrupt you can choose one among two sio implementation methods as follows: the first one is software sio: ? refer to user ? s manual chap 11 "contact/contactless i/o interf ace? the second one is uart, means hardware sio contact uart ? you can choose 12etu (t=0) or 11etu (t=1) transmission, change extra guard time (egt), choose parity bit for odd or even and select retry iteration number using cuartcon1, cuartcon2 contriol r egister ? through etu cycle registers, you can switch into more high or low baud rate. contactless uart ? using tbmod register, bit rate selection (106kbps, 212kbps), changing tr1 and egt from card to reader available for type b protocol.
