- **12 Programmable Counters:** Four onboard 82C54 timer/counter chips provide twelve 16-bit down counters. Ten counters operate independently, while two (counters #11 and #12) are cascaded to form a 32-bit timer. - **Flexible Counter Configuration:** Each counter can be configured as independent or cascaded. Clock sources can be selected from internal 8 MHz, external input, previous counter output, or programmable CK1 source. - **Cascaded 32-bit Timer:** Counters #11 and #12 are cascaded by default, providing a 32-bit timer with a fixed 8 MHz base clock for extended timing range. - **Programmable Clock Sources:** Each counter can select from four clock sources: 1. Onboard 8 MHz clock 2. External clock (up to 10 MHz)
