S3C24A0A RISC MICROPROCESSOR (Preliminary Spec)
MODEM INTERFACE SPECIAL REGISTERS
INTERRUPT REQUEST TO AP REGISTER (INT2AP)
Register
INT2AP
Address
0x41180000
R/W
Description
R/W Interrupt request to AP register
Reset Value
0x000007FE
INT2AP
Reserved
INT2AP_ADR
Bit
[31:11]
[10:0]
Description
Reserved
Modem interface requests the interrupt to AP when modem chip
writes this address. This interrupt is cleared by the interrupt
controller of AP.
Initial State
0
7FE
INTERRUPT REQUEST TO MODEM REGISTER (INT2MDM)
Register
INT2MDM
Address
0x41180004
R/W
Description
R/W Interrupt request to modem register
Reset Value
0x000007FF
INT2MDM
Reserved
INT2MDM_ADR
Bit
[31:11]
[10:0]
Description
Reserved
Modem interface requests the interrupt to modem chip when AP
writes this address and clears the interrupt when modem chip
reads this address.
Initial State
0
7FF
NOTE: It is recommended that AP writes data with byte access on the interrupt port because AP can overwrite the data in
INT2AP if there are INT2AP and INT2MDM sharing the same word.
