13.1.6
Reset Device (F6H)
This command resets the ISP1183 in the same way as an external hardware reset
through input RESET_N. All registers are initialized to their reset values.
Code (hex): F6 —
reset the device
Transaction —
none
13.2 Data flow commands
Data flow commands are used to manage the data transmission between USB
endpoints and the system microcontroller. Much of the data flow is initiated through
an interrupt to the microcontroller. The data flow commands are used to access the
endpoints and determine whether the endpoint FIFOs contain valid data.
Remark:
The IN buffer of an endpoint contains input data
for
the host. The OUT
buffer receives output data
from
the host.
13.2.1
Endpoint Buffer (R/W: 10H, 12H–1FH/01H–0FH)
This command accesses endpoint FIFO buffers for reading or writing. First, the buffer
pointer is reset to the beginning of the buffer. Following the command, a maximum of
(N + 2) bytes can be written or read, N representing the size of the endpoint buffer.
After each read or write action, the buffer pointer is automatically incremented by one
(8-bit bus width).
In DMA access, the first two bytes (the packet length) are skipped: transfers start at
the third byte of the endpoint buffer. When reading, the ISP1183 can detect the last
byte through the EOP condition. When writing to a bulk or interrupt endpoint, the
endpoint buffer must be completely filled before sending data to the host.
Remark:
Reading data after a Write Endpoint Buffer command or writing data after a
Read Endpoint Buffer command data will cause unpredictable behavior of the
ISP1183.
Code (hex): 01 to 0F —
write (control IN, endpoints 1 to 14)
Code (hex): 10, 12 to 1F —
read (control OUT, endpoints 1 to 14)
Transaction —
write or read maximum (N + 2) bytes (isochronous endpoint:
N
≤
1023, bulk or interrupt endpoint: N
≤
64)
The data in the endpoint FIFO must be organized as shown in
Table 24
. Examples of
endpoint FIFO access are given in
Table 25
.
