Address: 0x00d0_0004
DIVLD — Clock Divider Loaded Bit
PRDIV8 — Enable Prescaler Divide by 8 Bit
DIV[5:0] — Clock Divider Field
SGFMCLKD must be written with an appropriate value before
programming or erasing the FLASH array. Refer to
SGFMCLKD
The SGFM Test Register (SGFMTST) is unbanked and is used only for
factory testing.
Accesses to SGFMTST when not in test mode will result in a cycle
termination transfer error.

Read:
Write:
The combination of PRDIV8 and DIV[5:0] effectively divides the
SGFM input clock down to a frequency between 150 kHz and
200 kHz. The frequency range of the SGFM clock is 150 kHz to
102.4 MHz.
