NAME¶
mca_read_pos - read POS register from cardSYNOPSIS¶
unsigned
char mca_read_pos(int slot,
int reg);
ARGUMENTS¶
slotslot 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.AUTHORS¶
