3.3.3 Program Counter
The program counter (PC) is a 13-bit register that contains the address
of the next byte to be fetched.
3.3.4 Stack Pointer
The stack pointer (SP) contains the address of the next free location on
the stack. During an MCU reset or the reset stack pointer (RSP)
instruction, the stack pointer is set to location $00FF. The stack pointer
is then decremented as data is pushed onto the stack and incremented
as data is pulled from the stack.
When accessing memory, the seven most significant bits (MSB) are
permanently set to 0000011. These eight bits are appended to the six
least significant register bits (LSB) to produce an address within the
range of $00FF to $00C0. Subroutines and interrupts may use up to 64
(decimal) locations. If 64 locations are exceeded, the stack pointer
wraps around and loses the previously stored information. A subroutine
call occupies two locations on the stack; an interrupt uses five locations.
3.3.5 Condition Code Register
The condition code register (CCR) is a 5-bit register in which four bits are
used to indicate the results of the instruction just executed, and the fifth
bit indicates whether interrupts are masked. These bits can be tested
individually by a program, and specific actions can be taken as a result
of their state. Each bit is explained in the following paragraphs.
H — Half Carry
This bit is set during ADD and ADC operations to indicate that a carry
occurred between bits 3 and 4.
I — Interrupt
When this bit is set, the timer and external interrupt are masked
(disabled). If an interrupt occurs while this bit is set, the interrupt is
latched and processed as soon as the interrupt bit is cleared.
