А вот такой вопрос - для еще одной версии недоделанного девайса, получается нужно три uart

Т.е. будет три адресата. таких кристаллов не нашла, но может вместо одного можно как-то использовать BSL? Или это глупая версия? многопроцессорный формат разбирать сейчас не очень хочется...

Re: MSP430F417 UARTYou can call the asynchronous serial Receive-a-Character and
Transmit-a-Character subroutines in the BSL of a MSP430F417 under the
following conditions:
(a) You must set up and use P1.0 as the serial output.
(

You must set up and use P1.1 as the serial input.
© MCLK must be faster than 100*BAUD. For example, to use 9600b/s,
you need to have MCLK>0.96MHz.
(d) You need to set up the word at RAM 0x0202-0x0203 to [MCLK/BAUD].
For example, if MCLK=1MHz and BAUD=9600b/s, this word need to be 100
(0x0064).
(e) You need to set up the word at RAM 0x0204-0x0205 to
[(MCLK/BAUD)/2-30]. For example, if MCLK=1MHz and BAUD=9600b/s, this
word need to be 20 (0x00).
(f) You must set up TimerA to count in Continuous Mode. The counting
rate should be the same as MCLK.
(g) You can do either serial input or serial output. You cannot do
both at the same time.
(h) You cannot handle interrupts while doing either serial input or
serial output.
(i) You must use Even Parity. You have none, 1-byte or 2-byte
block-checksum options.
For the checksum options, do one of the followings:
(1) If you do not want checksum, set R9 to 0x1000 or 0x1001 before you
call the subroutines. The subroutines will change R9 from 0x1000 to
0x1001 and from 0x1001 to 0x1000. Thus subsequent calls do not need to
set R9 again.
(2) If you want a 1-byte XOR checksum, set R9 to 0 every time you call
the subroutines. The subroutines will update a 1-byte checksum at
0x0212 and change R9 to 1. You need to initialize and read the
checksum yourself.
(3) If you want a 2-byte XOR checksum, set R9 to 0 when you initialize
the checksum. The subroutines will update a 2-byte checksum at
0x0212-0x0213 and change R9 from 0 to 1 or from 1 to 0 to select which
byte to update. You need to initialize and read the checksum yourself
but you should not change R9.
In addition to the above, to Receive-a-Character, you do the following:
Код
CLR R11
CALL #0x0F56
The character will be returned in R12.
R11:BIT1 is an error flag.
R5 is destroyed.
RAM 0x0209 is destroyed.
To Transmit-a-Character, you do the following instead:
Код
MOV.B [Character], R12
CALL #0x0EEA
R11 is destroyed
R5 is destroyed
RAM 0x0207 is destroyed.
