14.12.8 SCANLADR

Scan Low Address Register
Note:
  1. Registers SCANLADRU/H/L form a 22-bit value, but are not guarded for atomic or asynchronous access; registers should only be read or written while SCANGO = 0.
  2. While SCANGO = 1, writing to this register is ignored.

Bits 21:16 – SCANLADRU[5:0] Scan Start/Current Address upper byte

Upper bits of the current address to be fetched from, value increments on each fetch of memory.

Bits 15:8 – SCANLADRH[7:0] Scan Start/Current Address high byte

High byte of the current address to be fetched from, value increments on each fetch of memory.

Bits 7:0 – SCANLADRL[7:0] Scan Start/Current Address low byte
