111 / 137 page ![]() Analog Integrated Circuit Device Data Freescale Semiconductor 111 PF0100 Functional Block Requirements and Behaviors Control Interface I2C Block Description 6.5.5.2 Embedded Memory There are four register banks of general purpose embedded memory to store critical data. The data written to MEMA[7:0], MEMB[7:0], MEMC[7:0], and MEMD[7:0] is maintained by the coin cell when the main battery is deeply discharged, removed, or contact-bounced. The contents of the embedded memory are reset by COINPORB. The banks can be used for any system need for bit retention with coin cell backup. Table 129.
