 The following AVMM interface signals are provided per HBM2 Pseudo Channel. 
  
 
  | Port Name | Direction | Width | Description | 
|---|---|---|---|
| ctrl_amm_0_0_waitrequest_n | Output | 1 | Asserts when HBM is busy. | 
| ctrl_amm_0_0_read | Input | 1 | Read request. | 
| ctrl_amm_0_0_write | Input | 1 | Write request. | 
| ctrl_amm_0_0_address | Input | 28/29 | Write or read address, 28-bits wide for 4G device, 29-bits wide for 8-G device. | 
| ctrl_amm_0_0_readdata | Output | 256 | Read data. | 
| ctrl_amm_0_0_writedata | Input | 256 | Write data. | 
| ctrl_amm_0_0_burstcount | Input | 7 | AVMM burst count, set to 7’h1 for BL4, 7’h2 for burst length 8. | 
| ctrl_amm_0_0_byteenable | Input | 32 | Byte-enable for write data. | 
| ctrl_amm_0_0_readdatavalid | Output | 1 | Asserts when read data is valid. | 
| ctrl_ecc_readdataerror_0_0 | Output | 1 | Asserts high by the controller ECC logic to indicate that the read data has an uncorrectable error. | 
| ctrl_auto_precharge_0_0 | Input | 1 | Available when the Enable Auto Precharge Control option is selected in Controller Configuration. When asserted high along with a read or write request to the memory controller, indicates that auto-precharge is enabled. | 
| ctrl_user_priority_0_0 | Input | 1 | Available when the Enable Command Priority Control option is selected in Controller Configuration. When asserted high along with a read or write request to the memory controller, indicates that the request is high priority and should be fulfilled before other low priority requests. |
