RDYRTNN
Ipd
Ready Return Not:
For VLBus-like mode: Asserted by the host to complete synchronous read cycles. If the
host doesn’t connect to this pin, assert this pin.
For burst mode (32-bit interface only): Host drives this pin low to signal waiting states.
12
BCLK
Ipd
Bus Interface Clock
Local bus clock for synchronous bus systems. Maximum frequency is 50MHz.
This pin should be tied Low or unconnected if it is in asynchronous mode.
13
DATACSN
Ipu
DATA Chip Select Not (For KSZ8841-32 Mode only)
Chip select signal for QMU data register (QDRH, QDRL), active Low.
When DATACSN is Low, the data path can be accessed regardless of the value of AEN,
A15-A1, and the content of the BANK select register.
14
PMEN
Opu
Power Management Event Not
When asserted (Low), this signal indicates that a power management event has occurred
in the system when a wake-up signal is detected by KSZ8841M.
