AMP(1,0) Analog In 2 Analog Inputs to Op-Amps ENV(1,0) STRAP 2 Environment select strap pins. These pins define the device environment. They are sampled on all resets except HMR. ENV2 is permanently high in the 100-pin package. ENV2 STRAP N/A 1 HA TTL 1 Host Address line used in conjunction with the chip- select inputs to address registers on the Host Interface. HIOR TTL 1 Host I/O Read. Active-low input that signals an I/O data read by the host processor. HIOW TTL 1 Host I/O Write. Active-low input that signals an I/O data write by the host processor. HCSA TTL 1 Host Chip Select A. Active-low input that indicates an access to Channel A by the host processor. HCSB TTL 1 Host Chip Select B. Active-low input that indicates an access to Channel B by the host processor. HMR Schmitt 1 Host Master Reset HPWRON Schmitt 1 Host Power On. Indicates that the host power supply is on, and the host bus interface signals are valid. While HPWRON is low, the host inputs are ignored, and all outputs float. NANDEN Schmitt 1 NAND Test Mode / ISE TRI-STATE Mode PFAIL Schmitt 1 Power Fail Detected Input RESET Schmitt 1 Master Reset. A low level resets the controller and inhibits HFCG frequency locking. RXD0-3 MII In 4 MII Input data. RX_CLK MII In 1 MII Receive Clock RX_DV MII In 1 MII Receive Data Valid RX_ER MII In 1 MII Receive Error COL MII In 1 MII Collision Detect CRS MII In 1 MII Carrier Sense TX_CLK MII In 1 Transmit Clock Input ISE Schmitt N/A 1 ISE Interrupt. reserved for use by the development system.
