6 / 14 page W523SXX (PRELIMINARY) - 6 - overwrite, or non-overwrite. The 8-bit structure of this register and the rising or falling edge of the triggers corresponding to each bit are shown above. “ X” indicates a “ don’ t care” bit. The TG1, 2, 5, 6 represents triggers 1, 2, 5 and 6 respectively; the “R” represents the rising edge; and “F” represents the falling edge. When any one of the eight bits is set to “1”, the rising or falling edge of the corresponding trigger pin can be enabled, interrupting the current state. 5. STOP Register BIT 7 6 5 4 3 2 1 0 STOP X X X STE STD STC STB STA The STOP register stores stop output status information to determine the voltage level of each stop output pin. The 8-bit structure of this register and the stop output pin corresponding to each bit are show as above table. The “X” indicates a “don’ t care” bit. When a particular STOP bit is set to “1”, the corresponding stop signal will be an active high output. 6. R0-R3 Registers These four registers are 8-bit register that stores the entry values of from 0 to 255 voice groups. R0 is a special register that can be incremented by "INC" instruction. Option Control Function There are four types of option control in W523Sxx. They can be determined by a declaration in the user ′s program file, but cannot be controlled by register. FUNCTION MASK OPTION DECLARATION DEFINITION DEFPAGE 1 256 interrupt vector/label for 1 page, 1 page in total (1-page mode) DEFPAGE 8 256 interrupt vector/label for 1 page, 8 pages in total (8-page mode) DEFPAGE 16 128 interrupt vector/label for 1 page, 16 pages in total (16-page mode) Page mode configuration DEFPAGE 32 64 interrupt vector/label for 1 page, 32 pages in total (32-page mode) NORMAL Normal mode operation Operation mode CPU CPU mode operation OSC_3MHz 3 MHz oscillator Oscillator frequency OSC_1.5MHz 1.5 MHz oscillator VOUT_DAC DAC (AUD) output Voice output type VOUT_PWM PWM output "DEFPAGE" determines the page operation mode in W523Sxx. The default setting of the page mode is 1-page mode. The 8-page, 16-page or 32-page mode can be declared to extend the voice group entry from 256 to 2047 in PowerSpeech ™ program. The W523Sxx can communicate with an external microprocessor through the simple serial CPU interface, which is the same as the W583xx series. The CPU interface consists of the TG1, TG2, and STPA/BUSY pins. "NORMAL" and "CPU" decide whether the operation mode of W523Sxx will be normal mode or CPU mode. "OSC_3MHz" and "OSC_1.5MHz" select the frequency of the system clock. "VOUT_DAC" and "VOUT_PWM" select the voice output type. |
