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.
