14.12.9 SCANHADR

Scan High Address Register

Note:

Registers SCANHADRU/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.
While SCANGO = 1, writing to this register is ignored.

Bits 21:16 – SCANHADRU[5:0] Scan End Address bits

Upper bits of the address at the end of the designated scan

Bits 15:8 – SCANHADRH[7:0] Scan End Address bits

High byte of the address at the end of the designated scan

Bits 7:0 – SCANHADRL[7:0] Scan End Address bits

Low byte of the address at the end of the designated scan

Registers SCANHADRU/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 Scanner GO bit(2, 3) = 0. While SCANGO Scanner GO bit(2, 3) = 1, writing to this register is ignored.
