Flash Programming Mode
There are two programming modes: parallel and serial.
The programming mode is selected by the state of the ALE
and PSEN signals during reset (BOR, WDT, software, or
POR). Serial programming mode is selected with PSEN =
0 and ALE = 1. Parallel programming mode is selected
with PSEN = 1 and ALE = 0, as shown in Figure 24. If they
are both high, the MSC1211/12/13/14 will operate in User
Application mode. For both signals, low is a reserved
mode and is not defined. Programming mode is exited with
a reset and the normal mode selected.
Figure 25 shows the serial programming conection.
Serial programming mode works through USART0, and
has special protocols. Table 7 describes these protocols,
which are discussed at length in Application Note
SBAA076 (available for download at www.ti.com). The
serial programming mode works at a maximum baud rate
determined by fOSC.
