Sends a write request (R/W pin low) to transceiver at the specified address with the specified byte of data. The primary reason of this instruction "packaging" is to obscure the complexity of appropriate delays to ensure proper signal latching.
Sends a write request (R/W pin low) to transceiver at the specified address with the specified byte of data. The primary reason of this instruction "packaging" was to obscure the complexity of appropriate delays to ensure proper signal latching. The delayed version is currently commented out under the assumption of falling edge of clock latching of data by the Transceiver.
