Description
UART receive data.
UART transmit data.
UART data terminal ready. Active low. Debug enable (factory test signal).
UART data set ready. Active low.
Normal mode: UART request to send. Active low output.
During reset: CPU clock select. Select CPU clock source. CPUCLKSEL=0 (normal
mode), the internal PLL clock output is used as the CPU clock source.
CPUCLKSEL=1 (factory test signal), the external clock to the CPUCLK pin is used as
the internal CPU clock source.
UART clear to send. BIST enable (factory test signal).
UART data carrier detect. Scan enable (factory test signal).
UART ring indicator. Chip test reset (factory test signal).
