1 _{IO_Code = 0x7 is not allowed for the SAP5 16 Pin version.}
2 _{Parameter Ports are parameter outputs during WPAR master calls and after DEXG master calls. They are in}
high impedance state after WPAR master calls and act as input when a DEXG master calls is performed.
4.10. Fault Indication Input PFAULT
The fault indication input PFAULT is provided for sensing a periphery fault-messaging signal. It contains a
high voltage high impedance input stage that sets the status bit S1 of the AS-i Slave to ‘1’ if it detects a LOW
level at the PFAULT pin. DC properties of the pin are specified at Table 16.
Signal transitions at the PFAULT pin become visible in S1 with a slight delay, because a clock synchronizing
circuit is located in between.
4.11. LED outputs
4.11.1. Slave Mode
The SAP5 provides two LED pins for enhanced status indication. LED1 and LED2 both comprise NMOS open
drain output drivers. In addition, LED2 contains a high voltage high impedance input stage for purposes of the
IC production test.
In order to comply with the signaling schemes defined in the AS-i Complete Specification a red LED shall be
connected to LED2 and a green LED shall be connected to LED1.
Following status indication is supported
