Preliminary
Figure 7-1 JTAG to FM Connection for LOCKOUT_RECOVERY
Two examples of FM_CLKDIV calculations follow.
EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been
set up, the input clock will be below 12.8MHz, so PRDIV8 = FM_CLKDIV[6] = 0. Using the
following equation yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a
clock of 190kHz. This translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively.
EXAMPLE 2: In this example, the system clock has been set up with a value of 32MHz, making
the FM input clock 16MHz. Because that is greater than 12.8MHz, PRDIV8 = FM_CLKDIV[6] =
1. Using the following equation yields a DIV value of 9 for a clock of 200kHz, and a DIV value of
10 for a clock of 181kHz. This translates to an FM_CLKDIV[6:0] value of $49 or $4A,
respectively.
Once the LOCKOUT_RECOVERY instruction has been shifted into the instruction register, the
clock divider value must be shifted into the corresponding 7-bit data register. After the data register
has been updated, the user must transition the TAP controller into the RUN-TEST/IDLE state for
the lockout sequence to commence. The controller must remain in this state until the erase
sequence has completed. For details, see the JTAG Section in the 56F8300 Peripheral User
Manual.
