MCA_READ_POS(9) Public Functions Provided MCA_READ_POS(9)NAMEmca_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.
