Table 82 Hardware Control Register

Notes

1. RSTx = 0 means reset condition if RSTO is asserted; ‘

−’ denotes not affected from reset line. During reset

(RST, RSTO) only those registers with an explicitly given reset value are affected. All other registers are undefined

and have to be set by the controller.

2. To clear these interrupt flags, the corresponding location has to be written with a logic 1.

Table 83 Real Time Clock registers

Note

1. RSTx = 0 means reset condition if RSTC is asserted; ‘

−’ denotes not affected from reset line. During reset

(RST, RSTC) only those registers with an explicitly given reset value are affected. All other registers are undefined

and have to be set by the controller.
