... Stack Pointer (SP) The Z86D99/Z86L99 family of products is configured for an internal stack. The size of the stack is limited only by the available memory space or general-purpose RAM registers dedicated to this task. An 8-bit stack pointer, as described in Table 17, is used for all stack operations. Table 17. SP Register [Group/Bank F0h, Register F (R255)] ...

... Low-Battery Detect Flag (LB) When the Z86D99/Z86L99 is used in a battery-operated application, one of the on-chip comparators can be used to check that the V correct operation of the device. When voltage begins to approach the V an on-chip low-battery detection circuit is tripped, which in turn sets a user-read- able flag. The LB register, as described in Table 18, is used to set and reset the LB flag ...
