Description
MUX_DIV[3:0]
2100[7:4]
0
R/W
MUX_DIV[3:0] is the number of ADC time slots in each MUX frame. The
maximum number of time slots is 11.
OPT_BB
2457[0]
0
R/W
Configures the input of the optical port to be a DIO pin to allow it to be
bit-banged. In this case, DIO5 becomes a third high speed UART. Refer to
2.5.7 UART and Optical Interface under the “Bit Banged Optical UART
(Third UART)” sub-heading on page 58.
OPT_FDC[1:0]
2457[5:4]
0
R/W
Selects OPT_TX modulation duty cycle.

OPT_RXDIS
2457[2]
0
R/W
OPT_RX can be configured as an input to the optical UART or as SEGDIO55.
OPT_RXDIS = 0 and LCD_MAP[55] = 0: OPT_RX
OPT_RXDIS = 1 and LCD_MAP[55] = 0: DIO55
OPT_RXDIS = 0 and LCD_MAP[55] = 1: SEG55
OPT_RXDIS = 1 and LCD_MAP[55] = 1: SEG55
OPT_RXINV
2457[1]
0
R/W
Inverts result from OPT_RX comparator when 1. Affects only the UART input.
Has no effect when OPT_RX is used as a DIO input.
OPT_TXE [1:0]
2456[3:2]
00 –
R/W
Configures the OPT_TX output pin.
If LCD_MAP[51] = 0:
00 = DIO51, 01 = OPT_TX, 10 = WPULSE, 11 = VARPULSE
If LCD_MAP[51] = 1:
xx = SEG51
OPT_TXINV
2456[0]
0
R/W Invert OPT_TX when 1. This inversion occurs before modulation.
OPT_TXMOD
2456[1]
0
R/W
Enables modulation of OPT_TX. When OPT_TXMOD is set, OPT_TX is
modulated when it would otherwise have been zero. The modulation is applied
after any inversion caused by OPT_TXINV.
OSC_COMP
28A0[5]
0
R/W
Enables the automatic update of RTC_P and RTC_Q every time the temperature
is measured.
PB_STATE
SFR F8[0]
0
R
The de-bounced state of the PB pin.
PERR_RD
PERR_WR
SFR FC[6]
SFR FC[5]
0
R/W
The IC sets these bits to indicate that a parity error on the remote sensor has
been detected. Once set, the bits are remembered until they are cleared by
the MPU.
PLL_OK
SFR F9[4]
0
R
Indicates that the clock generation PLL is settled.
