After timer is enable, the timer will start to count up. The Timer Interrupt is generated when the
TIMER register overflows from FFh to 00h.

The Program Counter (PC) is 11-bit wide. The low byte comes from the PCL register, which is a
readable and writable register. The high byte is not directly readable or writable and comes from
PCHBUF. The GL600USB has a 4 level deep x 11-bit wide hardware stake. The stake space is
not part of either program or data space and the stack pointer is not readable or writable. The PC
is pushed onto the stack when a CALL instruction is executed or an interrupt causes a branch. The
stack is poped in the event of a RETIA, RETI or a RET instruction execution. PCHBUF is not
affected by a push or pop operation.
Value on POR: “0 0 0 0 0 0 0 0”
