COMINIT
COMINIT always originates from the drive and requests a communication initialization. It is electrically identical to the
COMRESET signal except that it originates from the device and is sent to the host. It is used by the device to request a
reset from the host in accordance to the sequence shown in Figure 6, below.
Figure 6 : cominit sequence
Description:
1. Host/device are powered and operating normally with some form of active communication.
2. Some condition in the device causes the device to issues a COMINIT
3. Host calibrates and issues a COMWAKE.
4. Device responds – The device detects the COMWAKE sequence on its RX pair and calibrates its transmitter (optional).
Following calibration the device sends a six burst COMWAKE sequence and then sends a continuous stream of the
ALIGN sequence starting at the device's highest supported speed. After ALIGNP Dwords have been sent for 54.6 us (2048
nominal Gen1 Dword times) without a response from the host as determined by detection of ALIGNP primitives received
