Pin N_PWR_ON
ATA5823/ATA5824
(Status register)
To switch the transceiver from OFF to IDLE mode, pin N_PWR_ON must be set to 0 (maximum
0.2
tive edge and switches on DVCC and AVCC.
If V
sets the status bit N_Power_On to 1, an interrupt is issued (T
on pin CLK is available.
If the level on pin N_PWR_ON was set to 1 before the interrupt is issued, the transceiver stays in
OFF mode.
Note:
Figure 12-2. Timing Pin N_PWR_ON, Status Bit N_Power_On
N_POWER_ON
If the transceiver is in any of the active modes (IDLE, TX, RX, RX_Polling, FD), an integrated
debounce logic is active. If there is an event on pin N_PWR_ON, a debounce counter is set to 0
(T = 0) and started. The status is updated, an interrupt is issued and the debounce counter is
stopped after reaching the counter value T = 8195
An event on N_PWR_ON before reaching T = 8195
While the debounce counter is running, the bit CLK_ON in control register 3 is set to 1.
The interrupt is deleted after reading the status register or executes the command Delete_IRQ.
If pin N_PWR_ON is not used, it can be left open because of an internal pull-up resistor (typi-
cally 50 k ).

It is not possible to set the transceiver to OFF-mode by setting pin N_PWR_ON to 1. If pin
N_PWR_ON is not used, it should be left open because of the internal pull-up resistor
