APCLK2FAC
12:8
rw
Slow Down Clock Divider for TFILT_CLK Generation
This setting is effective only when the APCLK_SET = 1.
Other bit combinations equivalent.
Notes
1. If SYSCLKSEL[1] = ‘1’ (LP_CLK) the default APCLK2FAC = 8
is taken
2. if SYSCLKSEL[1:0] = “11” (fINTOSC 20/40M) and
OSC80MDIV[1] = 0 the value APCLK2FAC = 19 is taken
3. if SYCLKSEL[1:0] = “11” (fintOSC 20/40M) and
OSC80MDIV[1] = 1 the value APCLK2FAC = 9 is taken
4. f
SYS
is further divided by the APCLK2FAC factor to
generate TFILT_CLK. The clock should be always at 2
MHz.

Analog Module Clock Factor
This bit field defines the factor by which the system clock
is divided down, with respect to the synchronous MI_CLK
clock.

The APCLKFAC bit is not a protected bit. This setting is only
effective when APCLK_SET = 1.
Note: If SYSCLKSEL[1] = ‘1’ (LP_CLK) the default
APCLK1FAC = “00” is taken (divide by 1)
if SYCLKSEL[1:0] = “11” and OSC80MDIV = 0 the value
APCLK1FAC = “01” is taken
if SYSCLKSEL[1:0] = “11” and OSC80MDIV = 1 the value
APCLK1FAC = “00” is taken
