 .Nm OWLL_WRITE_ONE,
 .Nm OWLL_WRITE_ZERO,
 .Nm OWLL_READ_DATA,
 .Nm OWLL_REASET_AND_PRESENCE
 .Nd Dallas Semiconductor 1-Wire Link Layer Interface
 .Sh SYNOPSIS
 .Ft int
 .Fn OWLL_WRITE_ONE "device_t lldev" "struct ow_timing *timing"
 .Ft int
 .Fn OWLL_WRITE_ZERO "device_t lldev" "struct ow_timing *timing"
 .Ft int
 .Fn OWLL_READ_DATA "device_t lldev" "struct ow_timing *timing" "int *bit"
 .Ft int
 .Fn OWLL_RESET_AND_PRESENCE "device_t lldev" "struct ow_timing *timing" "int *bit"
 .Sh DESCRIPTION
 The
 .Nm
 interface provides access to the link layer of the Dallas
 Semiconductor 1-Wire from upper layers of the protocol.
 .Pp
 .Fn OWLL_WRITE_ONE
 and
 .Fn OWLL_WRITE_ZERO
-writes a one bitor a zero bit respectively on the 1-Wire bus.
+writes a one bit or a zero bit respectively on the 1-Wire bus.
 .Pp
 .Fn OWLL_READ_DATA
 reads one bit from the 1-Wire bus.
 This is often referred to as a
 .Dq Read Time Slot
 in the 1-Wire device data sheets.
 .Pp
 The
 .Fn OWLL_RESET_AND_PRESENCE
 function starts a reset sequence and detects if any device(s) are
 present on the bus.
 This is the beginning of all 1-Wire transactions.
 .Sh NOTES
 This interface is intended to be used only by the
 .Xr ow 4
 device to talk to the low-level bus.
 By convention, the device that implements this interface is called
 .Xr owc 4 .
 Only devices that implement
 .Xr own 9
 should call these interfaces.
