7. This function is not available
8. Set according to the General RTC mode or KeyInt RTC mode. Bonding internally for “TA” product as described on Page 7.
9. SDRAM address bit is 13bit including SDRADDR [12:11].
10. Set according to the frequency of XT1 (12/20/24/48 MHz).
Bonding internally for “TA’’ product as described on Page 5.
11. Audio clock is generated by one of PLL2 (1 V) or PLL3 (3 V).
One of PLL2 or PLL3 is available for “TA” and “RA” product. Please refer to Page 5 for more information.
Both of PLL2 and PLL3 are available for “XA”,“XB”, “XC” and “XD” products.
12. Audio clock is generated by one of PLL2 (1 V) or PLL3 (3 V).
One of PLL2 or PLL3 is available for “TA” and “RA” product. Please refer to Page 5 for more information.
Both of PLL2 and PLL3 are available for “XA”,“XB”, “XC” and “XD” products.
13. Analog ground is shared by PLL2 and PLL3.
14. Unused Input terminals and input state terminals of bidirectional should be set Pull−up/Down resister ON or connect to digital power supply or ground
(don’t let open).
