W83787IF
URIRSEL (Bit 3):
This bit select UART B operating in normal function or in IR function.
0 Select UART B as Infrared function.
1 Select UART B as normal function.
During power-on reset, the default value is set by Pin 92 (HURIRSEL) pulled high or low. This pin is
internal pull-high.
GIOSEL (Bit 2):
This bit select IDE function or GIO function.
0 Select the IDE pins definition compatible to W83787IF IDE pins definition.
1 Select the W83787IF IDE pins definition and general purpose I/O function.
During power-on reset, the default value is set by Pin 91 (HGIOSEL) pulled high or low. This pin is
pulled high internally.
RX2INV (Bit 1):
This bit is inverting or non-inverting the IR receiver data or SOUTB of UART B.
0 Non-inverting the SINB pin of UART B function or IRRX pin of IR function.
1 Inverting the SINB pin of UART B function or IRRX pin of IR function.
During the power-on reset, the default value is low.
TX2INV (Bit 0):
This bit is inverting or non-inverting IR transciever data or SINB of UART B.
0 Non-inverting the SINB pin of UART B or IRTX pin of IR function.
1 Inverting the SINB pin of UART B or IRTX pin of IR function.
During the power-on reset, the default value is low.
7.2.14 Configuration Register D (CR0D) EFER = 89H, EFIR = 0DH (R/W)
When 89H is loaded into EFER and 0DH is loaded into EFIR, the CR0D register can be accessed
through EFDR. The bit definitions are as follows:
7 65 4 3 210
Notes:
SIRTX1 SIRTX0 (Bit 7, 6):
These two bits select IRTX pin in the IR function.
00 or 11
IRTX2 (Pin 2, PDBDIR)
01
IRTX1 (Pin 43, SOUTB)
