7.17 Flow Control Trigger Level High (FLWCNTH)
This 8-bit register is used to store the receive FIFO high threshold levels to start/stop
transmission during hardware/software flow control. Table 29 shows transmission control
register bit settings; see Section 6.5.
[1]
For 32-byte FIFO mode, refer to Section 7.3 “FIFO Control Register (FCR)”.
7.18 Flow Control Trigger Level Low (FLWCNTL)
This 8-bit register is used to store the receive FIFO low threshold levels to start/stop
transmission during hardware/software flow control. Table 30 shows transmission control
register bit settings; see Section 6.5.
[1]
For 32-byte FIFO mode, refer to Section 7.3 “FIFO Control Register (FCR)”.
7.19 Clock prescaler (CLKPRES)
This register hold values for the clock prescaler.
