SLASEJ4C April 2017 – February 2023 PGA460
PRODUCTION DATA
The response operation of the PGA460 UART interface is initiated with the controller sending a response request. After the response request is received by the PGA460 device, the UART responds with the proper data of the command being requested. In a response operation, the controller does not generate a checksum Field, rather it is generated by the PGA460.
Because the data direction changes (controller to PGA460 followed by PGA460 to controller) and because of the amount of processing time required by the PGA460 device to respond, a response delay time of 1-bit period occurs between the response request and the PGA460 response on the UART.
#X2127 shows an example of the PGA460 response operation.
