TEL: (03) 5639977 FAX: (03) 5630118 Version History Specification Revision History Version EM78P569 3.7 3.8 3.9 4.0 Content Modify Multiplier function 1. Move DARES bit from bit7 to bit3. 2. Change instruction “MUL” “INT A” 1. Update Application Note 2. Add 17.91MHz main CLK 1. Add data RAM address auto-increase function 2. Add mclk/2 signal output. (output shared with PC0) 3. Add carry bit calculation function.(ADD, SUB) Modify the relative between VERSEL (code option) and PLUS (RA page2) Modify code option define. Add the OSC stable and reset timing diagram Remove IDLE mode Modify operating temperature 4.1 4.2 4.3 4.4 User Application Note (Before using this chip, take a look at the following description note, it includes important messages.) 1. There are some undefined bits in the registers. The values in these bits are unpredicted. These bits are not allowed to use. We use the symbol “-” in the spec to recognize them. 2. You will see some names for the register bits definitions. Some name will be appear very frequently in the whole spec. The following describes the meaning for the register’s definitions such as bit type, bit name, bit number and so on. RA PAGE0 7 RAB7 R/W -0 Bit type Bit name Bit number Register name and its page 6 RAB6 R/W -0 read/write (default value=0) 5 BAB5 R-1 4 RAB4 R/W -1 read/write (default value=1) 3 - 2 RAB2 R 1 RAB1 R-0 0 RAB0 R/W read/write (w/o default value) read only (w/o default value) (undefined) not allowed to use read only (default value=1) read only (default value=0) 3. Always set IOCC PAGE1 bit 1 = 1 otherwise partial ADC function cannot be used. For 8 bits resolution DAC, DAO pin will output corresponding voltage after write new data to DAC data buffer(RA PAGE1). For 10 bits resolution, DAO pin will output constant after change DAC most significant 2 bits (R5 PAGE1 bit6~7). DAO will output correct voltage after write data to least significant 8 bits. That is to say, when using 10 bits resolution DAC, user must write most significant 2 bits and least significant 8 bits in order. 5. Base on “VERSEL”(code option) equal 0 or 1, R8 page1 and RB page2’s define are different. “VERSEL” = 0: R8 page1 defined to data RAM address buffer RB page2 defined to multiplier’s Y data or Y address buffer (controlled by RA page2 bit5 “INDR”). RA page2 bit4(PLUS) determine RAM address auto increase or not (only for multiplier’s addressing). RA page2 bit7 is undefined. “VERSEL” = 1: R8 page1 is undefined. RA page2 bit4(PLUS) determine RAM address auto increase or not (for data RAM and multiplier’s addressing). RA page2 bit7(INS) determine . RB page2 defined to multiplier’s Y data, Y address or data RAM address buffer. 6. The carry bit’s initial value is un-know, please define the initial value before execute first ADD or SUB in.
