Mask Options
The mask programmable options are listed below. The op-
tions are programmed at the same time as the ROM pattern
to provide the user with hardware flexibility to a variety of os-
cillation and packaging configuration.
OPTION 1: CKI INPUT
= 1 Crystal (CKI/IO) CKO for crystal configuration
= 2 External (CKI/IO) CKO available as G7 input
= 3 R/C (CKI/IO) CKO available as G7 input
OPTION 2: BROWN OUT
= 1 Enable Brown Out Detection
= 2 Disable Brown Out Detection
OPTION 3: BONDING

= 1 28-pin DIP 28-pin DIP/SO
= 2 20-pin DIP/SO 20-pin DIP/SO
= 3 16-pin SO N/A
= 4 28-pin SO N/A
