Hardware CTS/RTS Handshake

HSS_CTS
HSS_TxD
Start of transmission delayed until HSS_CTS goes high
tCTSsetup
tCTShold
Start of transmission not delayed by HSS_CTS
t_CTSset-up: HSS_CTS setup time before HSS_RTS = 1.5T min.
t_CTShold: HSS_CTS hold time after START bit = 0 ns min.
T = 1/48 MHz.
When RTS/CTS hardware handshake is enabled, transmission can be held off by deasserting HSS_CTS at least 1.5T before
HSS_RTS. Transmission resumes when HSS_CTS returns HIGH. HSS_CTS must remain HIGH until START bit.
HSS_RTS is deasserted in the third data bit time.
An application may choose to hold HSS_CTS until HSS_RTS is deasserted, which always occurs after the START bit.
