Command and register summary
The functions and registers of ISP1161’s DC 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:
As the ISP1161 DC’s data bus is 16 bits wide:
•
•
•
1. Command phase: when address bit A0 = 1, the DC interprets the data on the
2. Data phase (optional): when address bit A0 = 0, the DC transfers the data on
The upper byte (bits D15 to D8) in command phase or the undefined byte in data
phase is 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.
lower byte of the bus (bits D7 to D0) as a command code. Commands without a
data phase are executed immediately.
the bus to or from a register or endpoint FIFO. Multi-byte registers are accessed
least significant byte/word first.
