3. PIC16C6X MICROCONTROLLER
PIC MICROCONTROLLER:
 All Currently used PIC controllers are Harvard architecture
microcontrollers.
 PIC designed by micro technology.
 It can access 8, 16, 32 bit data for application purpose.
 In past days PIC had ROM, EPROM like erasable memories
only.
 In recent PICs Flash memory used as program memory.
 Some PIC models are designed with internal reprogrammable
memory.

POWER ON RESET AND BROWN OUT RESET:
 Power on and brown out reset make sure that the chip operate only
when the supply within limit.
 In brown out reset mode, when the power supply goes below a
specified voltage it reset the PIC.
WATCH DOG TIMER:
 A watch dog timer reset the processor, if any malfunctions in the
software program and program deviates from normal operation.
INPUT/OUTPUT PORTS:
 Each port has a bidirectional capability, input and output ports are
Multiplexed with alternate functions for peripheral devices on the
microcontroller.

ANALOG TO DIGITAL CONVERSION ADC:
 An ADC converts an analog signal into an equivalent digital
values.
INTERRUPT CONTROL :
 PIC microcontroller has one vectored interrupt location ( i.e.
0004H) but has 12 independent interrupt source can control, when
the central processing unit will deal with each source.
 There is no interrupt priority, only one interrupt is served at a time.
However interrupts can be masked.
USART:
 A universal synchronous asynchronous receiver transmission
when the serial data is transmitted asynchronously, data stream is
generated with the transmitter clock.
 The receiver must synchronize the incoming data stream to the
receiver clock.

11. ARCHITECTURE OF PIC16C6X
EEPROM/OTP/ROM:
 EEPROM/OTP/ROM development is supported by
ultraviolet erasable, programmable EPROM parts.
 Both small and large production runs are supported by lower
cost one time programmable.
 A very large run, microchips also supports customers with
very low cost ROM parts.
PROGRAM MEMORY:
 The PIC16C61 addresses 1K x 14 of program memory.
 The PIC16C62/62A/R62/64/64A/R64 address 2K x 14 of
program memory,
 The PIC16C63/R63/65/65A/R65 devices address 4K x 14 of
program memory.
 The PIC16C66/67 address 8K x 14 program memory.

12. ARCHITECTURE OF PIC16C6X
STATUS REGISTER :
 The status register is a 8 bit register tat stores the status of the
processor. This is also stores carry zero and digit carry bits.
PROGRAM COUNTER STACK:
 An independent 8 level stack is used for the program counter. As
the program counter is 13 bit the stack is organized as 8 X 13 bit
registers. When an interrupt occurs the program counter is pushed
onto the stack.
FSR REGISTER:
 File selection register, is an 8 bit register used as data memory
address pointer. This is used in indirect addressing mode.
