Bank Select Register. These two bits are shared same
address so that Bank Select Register (BSR) can be
programmed to desired Bank in any Bank.
BNK_SEL<1:0> = 00 Select Bank 0.
BNK_SEL<1:0> = 01 Select Bank 1.
BNK_SEL<1:0> = Reserved.
BNK_SEL<1:0> = Reserved.
Receiver FIFO Threshold Level. It is to determine the
RXTH_I to become 1 when the Receiver FIFO Threshold
Level is equal or larger than the defined value shown as
follow.
RXFTL<1:0> = 00 -- 1 byte
RXFTL<1:0> = 01 -- 4 bytes
RXFTL<1:0> = 10 -- 8 bytes
RXFTL<1:0> = 11 -- 14 bytes
Timer Test. Write to 1, then reading the TMRL/TMRH will
return the programmed values of TMRL/TMRH, that is,
does not return down count counter value. This bit is for
test timer register.
Enable timer. Write to 1, enable the t imer
Setting this bit to a logical 1 resets the RX FIFO counter
logic to initial state. This bit will clear to a logical 0 by itself
after being set to a logical 1.
Timer input clock.
