4.3.2.1 Global Configuration
The following is a description of the Global Resources that are configured for the CY7C60123-PVXC
enCoRe II LV microcontroller. Care must be taken when modifying these values as they affect the
User Modules discussed below.
CPU Clock
This parameter is set to Internal (24 MHz). In order to run the CPU at 12 MHz, CPU Clock/N needs
to be set to ‘2’. This operating frequency provides for faster code execution so that when events are
detected the microcontroller can be put back into the sleep state quicker for improved power sav-
ings.
CPU Clock / N
This parameter is set to ‘2’ to provide a 12 MHz clock.
Timer Clock
This parameter is set to TCAP.
Timer Clock /N
This parameter is set to ‘4’.
Capture Clock
This parameter is set to Low Power (32 kHz).
Capture Clock /N
This parameter is set to ‘6’.
Capture Edge
This parameter is set to Latest.
8 Bit Capture Prescaler
This parameter is set to ‘1’.
CLKOUT Source
This parameter is set to Internal (24 MHz).
EFTB
This parameter is set to Enable.
Crystal OSC
This parameter is set to Disable.
Crystal OSC Xgm
This parameter is set to 000.
Low V Detect
This parameter is set to 2.63V–2.68V.
