Output enable/disable to segment output only pins (n = 0 to 4)
Disables segment output
Enables segment output
Cautions 1. SEGEN can be written only once after reset release.
2. For 78K0R/LF3, bits 1 to 7 must be set to 0. For 78K0R/LG3, bits 2 to 7 must be set to 0. For
78K0R/LH3, bits 5 to 7 must be set to 0.
The segment output only pins operated by SEGEN4 to SEGEN0 are as follows.
