Symbol
CTD[7:0]
Function
The core timer counter register bit 0 to bit 7. This is a read only status register in which contains
the current value of the 8-bit ripple counter. This counter is clocked by the CPU clock (E/4) and
can be used for various functions, including a software input capture. Extended time can be
achieved by using the timer overflow function to increment a variable to simulate a 16-bit
counter.

Therefore, when SFFR=22H, the MCU will perform the Sector-Erase, SFFR=44H, the MCU will perform the Chip-
Erase, and SFFR=88H, the MCU will perform the Byte-Program. For a detailed explanation of MCU flash control,
please refer to Section 5.1, “In-Application Programming” on page 21.
