System ArchitectureCP_INTREGThe CP_INTREG at 0xCB000008 is used to acknowledge and control interrupts relatedto the MMCI and UART ring indicator.Table 3-14 describes the register bits.Bits Name Access Function[31:5] Reserved Use read-modify-write to preserve value.Table 3-14 CP_INTREG register[3] CARDINSERT Write Signals that a MMC has been inserted. Write1 to acknowledge and clear the card insertedinterrupt.[2] RI1 Write Signals that UART1 ring indicator signal(RI1) has been asserted. Write 1 toacknowledge and clear.[1] RI0 Write Signals that UART0 ring indicator signal(RI0) has been asserted. Write 1 toacknowledge and clear.[0] WPROT Read This is the MMC write-protection status.This does not generate an interrupt.ARM DUI 0159B Copyright © 2002 ARM Limited. All rights reserved. 3-29
