Description
92
URXD
I
UART receive data.
94
UTXD
O
UART transmit data.
93
UDTRN/
O
UART data terminal ready. Active low. Debug enable (factory test signal).
DBGENN
95
UDSRN
I
UART data set ready. Active low.
96
URTSN/
O/I
Normal mode: UART request to send. Active low output.
CPUCLKSEL
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.
97
UCTSN/
I
UART clear to send. BIST enable (factory test signal).
BISTEN
98
UDCDN/
I
UART data carrier detect. Scan enable (factory test signal).
SCANEN
99
URIN/
I
UART ring indicator. Chip test reset (factory test signal).
