Name
mca_read_pos —
read POS register from card
Synopsis
unsigned char mca_read_pos ( | int slot, |
| | int reg); |
Arguments
slot
slot number to read from
reg
register to read from
Description
Fetch a POS value directly from the hardware to obtain the
current value. This is much slower than mca_read_stored_pos and
may not be invoked from interrupt context. It handles the
deep magic required for onboard devices transparently.
