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
-

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.
