SERIAL TEST INTERFACE
The ADuC7033 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 4 , 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
0xFFFF0880
Write only
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 is made to write to STICON.
STIKEY1 must be written with 0x00B9 immediately
after STICON is written to ensure the STICON write
sequence is completed successfully. If STIKEY0 is not
written, is written out of sequence, or is written incor-
rectly, any subsequent write to the STICON MMR
is ignored.

Write only
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 is made to write to STICON.
STIKEY0 must be written with 0x0007 immediately
before STICON is written to ensure the STICON
write sequence is completed successfully. If STIKEY1
is not written, is written out of sequence, or is
written incorrectly, any previous write to the
STICON MMR is ignored.
STIDAT0
0xFFFF088C
0x0000
Read/write
The STIDAT0 MMR is a 16-bit register that holds
the first and second data bytes that are to be trans-
mitted on the STI pin as soon as the STI port is
enabled. The first byte to be transmitted occupies
Bits[7:0] and the second byte occupies Bits[15:8].
STIDAT1
0xFFFF0890
0x0000
Read/write
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[7:0] and the fourth byte occupies Bits[15:8].
