39 / 88 page  Am186ED/EDLV Microcontrollers 39 PRELI M INARY D RA F T Table 8. Peripheral Control Block Register Map All unused addresses are reserved and should not be accessed. Notes: 1. The register has been modified from the Am186ES/ Am188ES microcontrollers. 2. The previous Memory Partition Register (MDRAM) has been removed and its functionality replaced with the CAS-before-RAS refresh mode.
