4.6.4 General IO AC characteristics
Output load supported for all other IO outputs such as GPIO outputs, PWM, UART is
50 pF max and 5 pF min.
UART interface supports maximum baud rate of 2 Mbaud when system clock
frequency is 32 MHz.
All GPIO and PWM outputs will get reflected within 1 system clock period of 30ns on
the output pins.
4.6.5 JTAG Interface AC characteristics
The JTAG interface is a 5-pin interface timed with respect to TCK input clock.
• TMS, TDI are inputs which are sampled by SoC on rising edge of TCK and is
expected to be driven by JTAG host on falling edge of TCK.
• TDO is output from SoC driven on falling edge of TCK and expected to be
sampled by JTAG host on rising edge of TCK.
• TRSTB is asynchronous signal.
Delays shown in the following table are with respect to SoC.
