mca_read_pos(9)
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.
