7. CIR RECEIVER PORT
7.1
7.1.1 Bank0.Reg0 - Receiver Buffer Registers (RBR) (Read)
Receiver Buffer Register is read only. When the CIR pulse train has been detected and passed by the
internal signal filter, the data sampled and shifted into shifter register will write into Receiver Buffer
Register. In the CIR, this port is only supports PIO mode and the address port is defined in the PnP.
7.1.2 Bank0.Reg1 - Interrupt Control Register (ICR)
Power on default <7:0> = 00000000 binary
7.1.3 Bank0.Reg2 - Interrupt Status Register (ISR)
Power on default <7:0> = 00000000 binary

Timer Interrupt. Set to 1 when timer count to 0. This bit
will be affected by (1) the timer registers are defined in
Bank4.Reg0 and Bank1.Reg0~1, (2) EN_TMR(Enable
Timer, in Bank0.Reg3.Bit2) should be set to 1, (3)
ENTMR_I (Enable Timer Interrupt, in Bank0.Reg1.Bit2)
should be set to 1.
Line-Status-Register interrupt. Set to 1 when overrun, or
parity bit, or stop bit, or silent byte detected error in the
Line Status Register (LSR) sets to 1. Clear to 0 when
LSR is read.
Receiver Thershold-Level Interrupt. Set to 1 when (1)
the Receiver Buffer Register (RBR) is equal or larger
than the threshold level, (2) RBR occurs time-out if the
receiver buffer register has valid data and below the
threshold level. Clear to 0 when RBR is less than
threshold level from reading RBR.
