Revision A1
*
BSDAC1
(8 bits)+
SBRM1
(4 bits): 12-bit PWM/BRM static DAC register. (See Section
K
.)
*
WDTCLR
: Watchdog-timer-clear register, no specific hardware but an address. Writing any value to
WDTCLR will clear the watchdog timer.
*
ADC
: Result of the A-to-D conversion.
*
HFCOUNTL
: Horizontal frequency counter register, low byte. (See Section
L.d
.)
*
HFCOUNTH
: Horizontal frequency counter register, high byte. (See Section
L.d
.)
*
VFCOUNTL
: Vertical frequency counter register, low byte. (See Section
L.d
.)
*
VFCOUNTH
: Vertical frequency counter register, high byte. (See Section
L.d
.)
*
PORT4
: Latch outputs (output only).
*
SOAREG
: Safe-Operation-Area register. (See Section
L.g
.)
*
SOACLR
: Safe-Operation-Area Clear register, no specific hardware but an address. Writing
anyvalue
to SOACLR will clear the SOA output (P1.5).
*
S1CON
: Serial Port 1 Control Register.
*
S1STA
: Serial Port 1 Status Register.
*
S1DAT
: Serial Port 1 Data Register.
*
S1ADR
: Serial Port 1 Address Register.
B. 16K Bytes Flash Memory
Programming the Flash memory will be described in section F.
C. 256 Bytes of On-Chip Data Memory
This data memory is mapped to external locations 00H to FFH and can only be accessed by the
"MOVX @Ri" instruction. Since no external data can be accessed by this chip, there is no need for
the external memory read/write control signals (
RD
,
WR
) as the "MOVX @Ri" instruction can only
be executed internally.
D. SPI (Synchronous Peripheral Interface) and RS232 Port: Serial Port 0
P3.0(RXD) and P3.1(TXD) can be used as a SPI port (serial port mode 0 of standard 80C51) or a
RS232 port (mode 1, 2 or 3).
The SPI port can be used to communicate to OSD chip, DAC ...
An RS232 port can be used to talk to auto-alignment system, by using an 18.432 MHz crystal,
aximun baud rate is 19200 bpS.
E. DDC Port (support DDC1/2B/2B+, with two slave address registers)
One DDC1 port to support DDC1
One I2C port support DDC2B/2B+: Serial Port 1
An Interrupt is generated when DSCL has a transition from high to low and then remains low for 12
clock periods.
