12. Commands and registers
The functions and registers of ISP1181 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
Table 15
.
A complete access consists of two phases:
1.
Command phase
: when address bit A0 = 1, the ISP1181 interprets the data on
the lower byte of the bus (bits D7 to D0) as a command code. Commands without
a data phase are executed immediately.
2.
Data phase (optional)
: when address bit A0 = 0, the ISP1181 transfers the data
on the bus to or from a register or endpoint FIFO. Multi-byte registers are
accessed least significant byte/word first.
The following applies for register or FIFO access in 16-bit bus mode:
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.
