7.8.5 SI Registers
The following paragraphs describe the SI registers.
7.8.5.1 SI GLOBAL MODE REGISTER (SIGMR). The 8-bit SIGMR defines the RAM divi-
sion modes. The SIGMR appears to the user as a memory-mapped, read-write register and
is cleared at reset.
Bits 7–4—Reserved
MOTOROLA
1) PROGRAMMING
1) INITIAL STATE
1) EXCHANGE
THE TSA USES THE FIRST PART OF
THE RAM, AND THE SHADOW IS
THE SECOND PART OF THE RAM.
CSRxn = 0
CSRRa = 0
CSRTa = 0
CSRRb = 0
CSRTb = 0
THE USER PROGRAMS THE
SHADOW RAM FOR THE NEW
Rx AND Tx ROUTE AND SETS CSRxn.
CSRRb = 1
CSRTb = 1
THE SI EXCHANGES BETWEEN THE
SHADOW RAM AND THE CURRENT-
ROUTE RAM AND RESETS CSRxn.
CSRRa = 0
CSRRb = 0
CSRTb = 0
CSRRa = 1
CSRTa = 1
CSRTa = 0
