14.12.8 SCANLADR

Scan Low Address Register

Note:

Registers SCANLADRU/H/L form a 22-bit value, but are not guarded for atomic or asynchronous access; registers may only be read or written while SCANGO = 0.
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

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

Registers SCANLADRU/H/L form a 22-bit value, but are not guarded for atomic or asynchronous access; registers may only be read or written while SCANGO Scanner GO bit(2, 3) = 0. While SCANGO Scanner GO bit(2, 3) = 1, writing to this register is ignored.
