第一个问题的答案。

请参考www.ti.com/.../slau056j.pdf 中 Scan IF Debug Register

Only the lower two bits should be written when writing to the

SIFDEBUG register and only MOV instructions should be used write to

SIFDEBUG. After writing the lower two bits, reading the SIFDEBUG contents

gives the user different information. After writing 00h to SIFDEBUG, reading

SIFDEBUG shows the last address read by the PSM. After writing 01h to

SIFDEBUG, reading SIFDEBUG shows the index of the TSM and the PSM bits

Q7 to Q0. After writing 02h to SIFDEBUG, reading SIFDEBUG shows the TSM

output. After writing 03h to SIFDEBUG, reading SIFDEBUG shows which DAC

register is selected and its contents.
