Read/write access, write protected by two key registers (STIKEY0 and STIKEY1). A write access to STICON is only
completed correctly if the following triple write sequence is followed:
1.
2.
3.
The STI control MMR is a 16-bit register that configures the mode of operation of the serial test interface.
GPIO_13 must be configured for STI operation in GP2CON for STI communications.
Description
Reserved. These bits are reserved for future use and should be written as 0 by user code.
State bits. Read only. If the interface is in the middle of a transmission, these bits are not 0.
Number of bytes to transmit. These bits select the number of bytes to be transmitted. User code must subsequently
write the bytes to be transmitted into the STIDAT0, STIDAT1, and STIDAT2 MMRs.
000 = 1-byte transmission.
001 = 2-byte transmission.
010 = 3-byte transmission.
011 = 4-byte transmission.
100 = 5-byte transmission.
101 = 6-byte transmission.
Reset serial test interface.
1 = resets the serial test interface. A subsequent read of STICON returns all 0s.
0 = operates in normal mode (default).
Serial test interface enable. This bit is set by user code.
1 = enables the serial test interface.
0 = disables the serial test interface.
STIKEY0 MMR is written with 0x0007.
STICON is written.
The sequence is completed by writing 0x00B9 to STIKEY1.
