SERIAL TEST INTERFACE
The ADuC7036 incorporates single-pin, serial test interface
(STI) ports that can be used for end-customer evaluation or
diagnostics on finished production units.
The STI port transmits from one byte to six bytes of data in 12-bit
packets. As shown in Figure 44, each transmission packet includes
a start bit, the transmitted byte (eight bits), an even parity bit, and
two stop bits. The STI data is transmitted on the STI pin, and
the baud rate is determined by the overflow rate of Timer4.
The STI port is configured and controlled via six MMRs.
STIKEY0: Serial Test Interface Key0
STIKEY1: Serial Test Interface Key1
STIDAT0: Data0 (16-bit) holds two bytes
STIDAT1: Data1 (16-bit) holds two bytes
STIDAT2: Data2 (16-bit) holds two bytes
STICON: controls the serial test interface
Serial Test Interface Key0 Register
Name: STIKEY0
Address: 0xFFFF0880
Access: Write only
Function: The STIKEY0 MMR is used in conjunction with the
STIKEY1 MMR to protect the STICON MMR. STIKEY0 must
be written with 0x0007 immediately before any attempt to write
to STICON. STIKEY1 must be written with 0x00B9 immedi-
ately after STICON is written to ensure the STICON write
sequence completes successfully. If STIKEY0 is not written, is
written out of sequence, or is written incorrectly, any subsequent
write to the STICON MMR is ignored.
Serial Test Interface Key1 Register
Name: STIKEY1
Address: 0xFFFF0888
Access: Write only
Function: The STIKEY1 MMR is used in conjunction with the
STIKEY0 MMR to protect the STICON MMR. STIKEY1 must
be written with 0x00B9 immediately after any attempt to write to
STICON. STIKEY0 must be written with 0x0007 immediately
before STICON is written to ensure the STICON write sequence
complets successfully. If STIKEY1 is not written, is written out
of sequence, or is written incorrectly, any previous write to the
STICON MMR is ignored.
Serial Test Interface Data0 Register
Name: STIDAT0
Address: 0xFFFF088C
Default Value: 0x0000
Access: Read/write
Function: The STIDAT0 MMR is a 16-bit register that holds the
first and second data bytes that are to be transmitted on the STI pin
as soon as the STI port is enabled. The first byte to be transmitted
occupies Bits[0:7], and the second byte occupies Bits[8:15].
Serial Test Interface Data1 Register
Name: STIDAT1
Address: 0xFFFF0890
Default Value: 0x0000
Access: Read/write
Function: The STIDAT1 MMR is a 16-bit register that holds the
third and fourth data bytes that are to be transmitted on the STI pin
when the STI port is enabled. The third byte to be transmitted
occupies Bits[0:7], and the fourth byte occupies Bits[8:15].
Serial Test Interface Data2 Register
Name: STIDAT2
Address: 0xFFFF0894
Default Value: 0x0000
Access: Read/write
Function: The STIDAT2 MMR is a 16-bit register that is used to
hold the fifth and sixth data bytes that are to be transmitted on
the STI pin when the STI port is enabled. The fifth byte to be
transmitted occupies Bits[0:7], and the sixth byte occupies
Bits[8:15].
