11. Serial interface engine command description
UM10237_4
User manual
The functions and registers of the Serial Interface Engine (SIE) are accessed using
commands, which consist of a command code followed by optional data bytes (read or
write action). The USBCmdCode
registers are used for these accesses.
A complete access consists of two phases:
An overview of the available commands is given in
Here is an example of the Read Current Frame Number command (reading 2 bytes):
USBDevIntClr = 0x30;
USBCmdCode = 0x00F50500;
while (!(USBDevIntSt & 0x10)); // Wait for CCEMPTY.
USBDevIntClr = 0x10;
USBCmdCode = 0x00F50200;
while (!(USBDevIntSt & 0x20)); // Wait for CDFULL.
USBDevIntClr = 0x20;
CurFrameNum = USBCmdData;
USBCmdCode = 0x00F50200;
while (!(USBDevIntSt & 0x20)); // Wait for CDFULL.
Temp = USBCmdData;
USBDevIntClr = 0x20;
CurFrameNum = CurFrameNum | (Temp << 8);
Here is an example of the Set Address command (writing 1 byte):
USBDevIntClr = 0x10;
USBCmdCode = 0x00D00500;
while (!(USBDevIntSt & 0x10)); // Wait for CCEMPTY.
USBDevIntClr = 0x10;
USBCmdCode = 0x008A0100;
while (!(USBDevIntSt & 0x10)); // Wait for CCEMPTY.
USBDevIntClr = 0x10;
1. Command phase: the USBCmdCode register is written with the CMD_PHASE field
2. Data phase (optional): for writes, the USBCmdCode register is written with the
set to the value 0x05 (Command), and the CMD_CODE field set to the desired
command code. On completion of the command, the CCEMPTY bit of USBDevIntSt is
set.
CMD_PHASE field set to the value 0x01 (Write), and the CMD_WDATA field set with
the desired write data. On completion of the write, the CCEMPTY bit of USBDevIntSt
is set. For reads, USBCmdCode register is written with the CMD_PHASE field set to
the value 0x02 (Read), and the CMD_CODE field set with command code the read
corresponds to. On completion of the read, the CDFULL bit of USBDevInSt will be set,
indicating the data is available for reading in the USBCmdData register. In the case of
multi-byte registers, the least significant byte is accessed first.
