9.3.3
Read Current Frame Number
Reports the frame number (11 bits) of the last successfully received Start Of Frame
(SOF). It is followed by one or two data reads containing the frame number. Byte 1
contains the least significant bits of the frame number (bits 7 to 0), byte 2 holds the
most significant bits (bits 10 to 8) padded with zeroes (see
Table 38
).
Code (Hex) —
F5
Transaction —
read 1 or 2 bytes.
9.3.4
Read Embedded Port Status
Returns the Embedded Port Status register contents, see
Table 39
and
Table 40
.
When the SuspendChange or BusReset bit is logic 1, the corresponding bit in the
Interrupt register is set (see
Table 27
and
Table 28
) and a microcontroller interrupt is
generated. This command resets the SuspendChange, ConnectChange and
BusReset bits.
Code (Hex) —
E0 to E2 (embedded function 1 to 3)
Transaction —
read 1 byte.
9.3.5
Write Embedded Port Status
Changes the Embedded Port Status register. Contents of read-only bits are ignored.
Code (Hex) —
E0 to E2 (embedded function 1 to 3)
Transaction —
write 1 byte.
2
Suspend
Upon reading this bit indicates the current ‘suspend’ status: A logic 1 indicates
that no activity occurred on the upstream port for more than 3 ms. Any activity on
the upstream port will reset this bit to logic 0.
Writing a logic 0 into this bit will generate a remote wake-up, if the device is
suspended (Suspend = 1). Otherwise, writing a logic 0 has no effect.
Remark:
Writing a logic 1 never has any effect.
A logic 1 signals that the value of the Connect bit has changed. This bit is cleared
when it is read.
Writing a logic 1 causes the device to connect its pull-up resistor to the upstream
port, a logic 0 disconnects the pull-up resistor. Upon reading this bit indicates the
current ‘connect’ status.
