Hardware 3.10.5 On-chip RAM: special features The on-chip RAM is part of the microprocessor. It can be addressed by individual bits. Accesses to this type of me- mory are about twice as fast as accesses to the external ty- pes of memory, i.e. S-RAM and NV-RAM. The on-chip RAM is therefore fully occupied. Addresses are assigned to the following operands: Ш 32 inputs (I00.00...I01.15) Ш 32 outputs (O00.00...O01.15) Ш 40 markers (M00.00...M02.07) 34
