Analog System Clocking Signals
A system-clocking signal that is driven by the clock output of a digital PSoC block and can be selected
by the user to drive the clocking signal to an analog column. Any of the 8 digital PSoC blocks can be
muxed into this line using the ACLK0[2:0] bits in the Analog Clock Select Register (CLK_CR1).
A system-clocking signal that is driven by the clock output of a digital PSoC block and can be selected
by the user to drive the clocking signal to an analog column. Any of the 8 digital PSoC blocks can be
muxed into this line using the ACLK1[2:0] bits in the Analog Clock Select Register (CLK_CR1).
A system-clocking signal that can drive all analog PSoC blocks in Analog Column 0. This signal is
derived from the muxed input of the 24V1 , 24V2 , ACLK0 , and ACLK1 system clock signals. The output
of this mux is then passed through a 1:4 divider to reduce the frequency by a factor of 4. The
Acolumn0[1:0] bits in the CLK_CR0 Register determine the selected Column Clock.
A system-clocking signal that can drive all analog PSoC blocks in Analog Column 1. This signal is
derived from the muxed input of the 24V1 , 24V2 , ACLK0 , and ACLK1 system clock signals. The output
of this mux is then passed through a 1:4 divider to reduce the frequency by a factor of 4.The
Acolumn1[1:0] bits in the CLK_CR0 Register determine the selected Column Clock.
A system-clocking signal that can drive all analog PSoC blocks in Analog Column 2. This signal is
derived from the muxed input of the 24V1 , 24V2 , ACLK0 , and ACLK1 system clock signals. The output
of this mux is then passed through a 1:4 divider to reduce the frequency by a factor of 4. The
Acolumn2[1:0] bits in the CLK_CR0 Register determine the selected Column Clock.
A system-clocking signal that can drive all analog PSoC blocks in Analog Column 3. This signal is
derived from the muxed input of the 24V1 , 24V2 , ACLK0 , and ACLK1 system clock signals. The output
of this mux is then passed through a 1:4 divider to reduce the frequency by a factor of 4. The
Acolumn3[1:0] bits in the CLK_CR0 Register determine the selected Column Clock.
