ZLP12840 OTP MCU

Product Specification

The upper nibble of the register pointer (see Table 17) selects which working register

group, of 16 bytes in the register file, is accessed out of the possible 256. The lower nibble

selects the expanded register file bank and, in the case of the Crimzon ZLP12840 MCU

family, banks 0, 1, 2, 3, F, and D are implemented. A ð¸ in the lower nibble allows the

normal register file (Bank 0) to be addressed. Any other value from ðï¸ to ðÚ¸ exchanges

the lower 16 registers to an expanded register bank. See Table 17.
