using USART in AT91SAM7S256…

receiver is not getting enabled…RXRDY remains 0.

If transmitter works (i.e. clocks are ON) then ensure that:

  • USART pins are multiplexed correctly also for RX direction (disable PIO from controlling RX pin)

  • Multiplex RX I/O line to correct peripheral function (A/B)

  • Enable USART (transmitter and) receiver (US_CR)

I have AT91SAM7X256 development board and once above mentioned settings are correct then bidirectional data communication works with 115k2/8/N/1 settings i.e. once at least one character is received then RXRDY goes to 1 in US_CSR register.
