A two-bit field storing a value from 0 to 3 specifying the direction the redstone repeater is facing:

| 0x4 0x8 |
A two-bit field storing a value from 0 to 3 specifying the redstone repeater's delay:
|
Effectively, add the repeater's facing value (0 to 3) to 4×(delay-1). For example, a repeater facing west with a delay of 3 redstone ticks would have a block data value of 3 + 4×(3-1) = 11.
