commit 2d4a7dfd46d28bddd6df2a9c52c397e1b965a14a Author: raiden00pl <[email protected]> AuthorDate: Wed Nov 4 15:46:47 2026 +0100 arch/arm/nrf53: Start the IEEE 802.15.4 ACK at aTurnaroundTime. The ACK TX was started from two interrupts and went on air late. RADIO PHYEND starts the idle 802.15.4 timer over DPPI and its ACK compare enables TX.
