To switch from the 12-MHz SCLK to 32.768 kHz, use the following procedure:
1.
2.
3.
4.
Wait for one second (1s) for the 12-MHz PLL to stabilize (about 50000 clock
cycles). The delay depends on the external PLL filter and CAN vary significantly.
Switch the SCLK to a fast clock (set Fast/Slow bit R1(1)<0> to 1).
Simultaneously set the H_Position field R6(1)<3:0> to 0FH and the No_Switch
field R6(1)<4> to 1 (no clock switch).
Switch the SCLK to a 32.768-kHz clock (set Fast/Slow bit R1(1)<0> to 0).
Wait for more than R2(0)<7:0> + 256 clock cycles (approximately 32 mS) for the
SCLK to be switched.
Set the HSYNC_DELAY field R6(1)<3:0> to 0FH.
Disable the primary and secondary VCOs (set the Fast_enable bit R1(1)<1> to 0).
