43 / 89 page  2003 Oct 01 43 Philips Semiconductors Product specification CD audio decoder, digital servo and filterless DAC with integrated pre-amp and laser control SAA7824 handbook, full pagewidth DATA1 DATA2 DATA3 COMMAND SILD (microcontroller) SILD (microcontroller) SCL (microcontroller) SDA (microcontroller) SD (SAA782X) SD (SAA782X) D7 D6 D5 D4 D3 D2 D1 D0 data byte microcontroller read (one data byte) microcontroller read (full command) MBL450 Fig.33 Microcontroller protocol for read servo commands. 7.17.3 DECODER AND SHADOW REGISTERS To maintain compatibility with the SAA732x series, decoder registers 0 to F and the shadow registers are largely unchanged. However, to control the extra functionality of SAA7824, the shadow registers have been extended to include new shadow registers. All shadow registers are accessed by using the two LSBs (bits 0 and 1) of decoder register F. These bits are called SHADEN1 and SHADEN2 respectively. These bits are decoded according to Table 15. This two bit encoding allows the use of three shadow register banks; bank 1 (SAA732X shadow registers), and banks 2 and 3 (new shadow registers). Only the four addresses 3, 7, A and C are implemented in any one bank. Any other addresses sent while accessing any of the shadow register banks are invalid and have no effect. When SHADEN1 and SHADEN2 are both set to logic 0 (decoder register F set to XX00) all subsequent addresses are decoded by the main decoder registers again. Access to decoder register F is always enabled so that SHADEN1 and SHADEN2 can be set or reset as required. The SHADEN bits and subsequent shadow registers are programmed identically to the main decoder registers, i.e. they can be directly programmed when using the SAA7824 in 4-wire mode or programmed via the servo interface when using 3-wire or I2C-bus modes. The main decoder registers are given in Table 16 and the shadow registers in Table 18. Details of the new shadow registers can be found in Tables 19 to 22. |
