PCMCIA configuration register access
Tobias Metzger
I am trying to get access to the configuration register (see CISTPL_CONFIG
below) and the attribute memory (see CISTPL_DEVICE_A below) of our PCMCIA
Microcontroller-Card (PC-Card). The description of where the register is, is in
the CIS of the PC-Card.
I know how to get the address of the mapped common memory of th PC-Card, by
using the function CONFIGMG_Get_First_Log_Conf() of the VtoolsD library.
Does the configuration manager map the configuration register and the attribute
memory just like the common memory of the PC-Card?
Where can I find the addresses?
