Command and register summary
Table 12:
The functions and registers of ISP1181B are accessed via commands, which consist
of a command code followed by optional data bytes (read or write action). An
overview of the available commands and registers is given in
A complete access consists of two phases:
The following applies for register or FIFO access in 16-bit bus mode:

1. Command phase: when address bit A0 = 1, the ISP1181B interprets the data on
2. Data phase (optional): when address bit A0 = 0, the ISP1181B transfers the
The upper byte (bits D15 to D8) in command phase or the undefined byte in data
phase are ignored.
The access of registers is word-aligned: byte access is not allowed.
If the packet length is odd, the upper byte of the last word in an IN endpoint buffer
is not transmitted to the host. When reading from an OUT endpoint buffer, the
upper byte of the last word must be ignored by the firmware. The packet length is
stored in the first 2 bytes of the endpoint buffer.

data phase are executed immediately.
